How to Lace Hiking Boots Like a Pro: 6 Techniques Step by Step

To lace hiking boots properly, pull the slack out of the laces from the toe upwards, keep the forefoot snug but not tight, lock the tension at the ankle with a surgeon’s knot, and finish with a correctly tied (not “granny”) bow. Then fix specific problems with specific techniques: a heel lock for heel slip, window lacing for pressure on the top of the foot, and toe-relief lacing for squashed toes.

This guide walks through each method step by step, explains how to adjust your laces for long climbs and steep descents, and covers the knots that actually stay tied on the trail.

Quick answer: which lacing technique do you need?

Problem	Technique	What it does
General fit, new boots	Standard criss-cross with a surgeon’s knot at the ankle	Even pressure over the foot, locked ankle tension
Heel lifting, blisters on the back of the heel	Heel lock (lace lock)	Pulls the heel back into the heel cup
Pressure or numbness across the top of the foot, high arches	Window (box) lacing	Removes the crossing over the sore spot
Toes pressed, bruised toenails, wide forefoot	Toe-relief lacing	Opens up the toe box
Big-toe pressure only	Diagonal lacing	Lifts the upper away from the big toe
Toes hitting the front on descents	Tighter lower laces plus a heel lock	Stops the foot sliding forward
Laces coming undone	Check for a granny knot; use a double bow or surgeon’s start	A balanced knot that holds

Why lacing matters more in boots than in trainers

A trekking boot has to hold your foot still while you climb, descend and carry a pack, often for six to eight hours a day. If the foot moves inside the boot, you get friction, and friction causes blisters. If the laces are too tight, you restrict blood flow and press on the nerves and tendons that run across the top of the foot.

Good lacing solves both problems. It holds the heel firmly in the heel cup, lets the forefoot spread naturally and keeps the tension where you need it. It is also the one bit of fit you can adjust on the trail, mid-trek, without tools.

One caveat: lacing tweaks fine-tune a fit, they do not rescue the wrong boot. If your toes always hurt or your heel slips whatever you do, the size, width or last is probably wrong. Our guide to choosing trekking shoes covers fit in detail.

Know your boot: eyelets, hooks and the ankle “lock point”

Most mid- and high-cut hiking boots have two kinds of lace anchor:

• Eyelets or webbing loops over the forefoot. The lace runs through them, so tension spreads along the lacing.
• Open hooks around the ankle. The lace wraps around them, which lets you set different tension above and below.

Many boots also have a locking eyelet or locking hook at the point where the foot flexes, usually where the eyelets change to hooks. It grips the lace so the tension you set in the forefoot does not creep up into the ankle, and vice versa. If your boots have one, use it. If they do not, a surgeon’s knot at the same point does the same job.

How to lace hiking boots: the standard criss-cross method

This is the foundation for every other technique. Do it with the socks you will hike in, sitting down, with your heel pressed back into the boot.

1. Loosen everything. Open the laces right down to the toe so you can slide your foot in without forcing the heel counter.
2. Seat your heel. Put the boot on, then tap the heel on the ground or flex your ankle back so your heel sits snugly in the heel cup.
3. Remove slack from the bottom up. Starting at the lowest eyelets, pull each crossing gently snug, working one pair at a time towards the ankle. Snug means the upper is in contact with your foot without squeezing it.
4. Criss-cross the forefoot. Cross the laces over each other and feed them through the next pair of eyelets, from the outside in or inside out, but keep it the same on both sides.
5. Lock at the flex point. Where the forefoot meets the ankle, tie a surgeon’s knot (cross the laces and wrap them around each other twice) and pull it tight. This locks the forefoot tension.
6. Lace the ankle hooks. Continue crossing over and wrap each lace over and around the hooks from the top so it bites. Set the ankle tension to suit the terrain (see uphill and downhill below).
7. Tie a balanced bow and tuck in the loose ends so they cannot catch on the opposite boot or vegetation.
8. Walk and re-check. Walk around, find a slope or stairs if you can, and adjust. Laces settle in the first 15 to 30 minutes of walking, so recheck at your first rest stop.

How tight is right? You should be able to slide a finger under the laces at the top of the foot with a little effort. Numbness, tingling or a throbbing ache on top of the foot means too tight. A heel that lifts more than a few millimetres when you walk uphill means too loose.

Surgeon’s knot: the key to locking tension

The surgeon’s knot is simply a half knot with an extra wrap. That second turn adds friction, so the knot holds its position while you lace the rest of the boot. It is the most useful single thing to learn about boot lacing.

1. Pull the laces snug up to the point where you want to lock the tension.
2. Cross the laces over each other as if starting a normal knot.
3. Wrap one lace around the other a second time.
4. Pull both ends firmly outwards. The knot should stay put on its own.
5. Run each lace straight up to the next hook or eyelet (rather than crossing) to hold the lock, then continue lacing.

You can use two surgeon’s knots on the same boot, for example at the bottom and top edges of a window, to create zones with different tension. Leave space between them so you are not creating a tight band around the foot.

Heel lock lacing: stop heel slip and blisters

Heel slip is the main cause of blisters on the back of the heel, especially on long climbs. The heel lock (also called a lace lock or runner’s loop) pulls the ankle collar back and holds the heel in the cup. It also helps hikers with narrow heels or low-volume feet.

1. Lace normally up to the last pair of hooks or eyelets below the top. Leave the top pair empty for now.
2. On each side, run the lace straight up (not across) to the top hook on the same side, wrapping it over and around so it creates a small loop or vertical section between the two hooks.
3. Cross the laces over and feed each one under the vertical section on the opposite side.
4. Pull the ends down and outwards. You will feel the collar tighten around the ankle and the heel pull back.
5. Tie your bow as normal.

Some brands and retailers teach a version that uses a surgeon’s knot in the two pairs of hooks nearest the ankle bend instead. Both approaches work; use whichever holds your heel best.

Window lacing: relieve pressure on the top of the foot

If you have high arches, a prominent bone on the top of your foot, or swelling at a particular spot (common on long descents), a lace crossing directly over that point can cause aching and even numbness in the toes. Window lacing, sometimes called box lacing, removes that crossing.

1. Unlace the boot down to the eyelets just below the pressure point.
2. Instead of crossing over, run each lace straight up the same side to the next eyelet or hook.
3. Resume criss-cross lacing above the sore spot.
4. For a firmer hold, tie a surgeon’s knot at the bottom and top of the window so the tension either side does not pull through.

You can open a window anywhere along the lacing and make it as long as one or two eyelet pairs. If you need a very long window, the boot is probably too low in volume for your foot.

Toe-relief lacing: more room in the toe box

If your toes feel crushed, your forefoot is wide, or your toenails are bruising, you can open up the toe box by changing how the bottom of the boot is laced.

1. Unlace the boot completely.
2. Skip the lowest pair of eyelets and start lacing from the second pair.
3. Lace the rest of the boot as normal, keeping the lower section slightly looser than the upper.
4. Lock the ankle with a surgeon’s knot so the heel stays held even though the forefoot is relaxed.

This is best treated as a temporary fix to get you home in comfort. If you need toe-relief lacing every day, look for a boot with a wider toe box.

Diagonal lacing: big-toe pressure

A narrower variation targets pressure on the big toe, which can cause bruising under the nail and, in time, toenail loss.

1. Unlace the boot completely.
2. Run one end of the lace from the lowest eyelet on the outside of the boot diagonally to the top eyelet on the inner side (by the ankle).
3. Criss-cross the other end up through the remaining eyelets as normal.
4. When you tighten the long diagonal lace, it lifts the upper away from the big toe.

Uphill vs downhill: adjusting your laces on the trail

The same lacing does not suit every gradient. On a long trek with big climbs and descents, such as the trail between Lukla and Namche Bazaar, it is worth stopping to re-lace at the top and bottom of major sections.

Terrain	Forefoot laces	Ankle laces	Why
Long climbs	Snug	Slightly looser	Lets the ankle flex forward and reduces pressure on the Achilles and shin
Steep descents	Firm	Firm, with a heel lock	Stops the foot sliding forward and the toes hitting the front of the boot
Flat or rolling trail	Snug	Moderate	Balance of support and comfort
Rocky, uneven ground	Snug	Firm	More ankle support and stability

Descents are where most toe injuries happen. On days with long downhill sections, such as coming back down from Annapurna Base Camp through Chhomrong, tighten the laces before you start descending, not halfway down. Trekking poles also take a lot of load off the toes and knees going down; see how to pick trekking poles and how to train for downhill hiking.

Which knot stays tied? Avoiding the granny knot

A normal shoelace bow is a reef (square) knot with two slipped loops. If you tie the second half of the knot in the same direction as the first, you get a granny knot instead, which is far less secure. A quick check: a correctly tied bow sits across the boot, horizontally. A granny bow twists so its loops point up and down the boot.

Research from the University of California, Berkeley, published in Proceedings of the Royal Society A in 2017, found that shoelace knots fail through a combination of the foot striking the ground and the swinging leg pulling on the free ends. Once a knot starts to loosen, it can fail in just a couple of strides, and in their tests the granny-based bow came undone more readily than the reef-based one. Neither is immune, which is why tension at the base of the bow matters too.

To get a knot that lasts a full trekking day:

• Fix a granny knot by starting the knot the other way round (right over left instead of left over right), while tying the bow the way you normally do.
• Use a double bow: wrap the loop around twice before pulling it through. It looks almost the same and still unties with a firm pull on the ends.
• Start with a surgeon’s knot at the top so the base of the bow cannot loosen.
• Avoid tying a double knot over the bow if you can. It holds, but it is hard to undo with cold fingers or gloves, and tends to jam when the laces are wet or muddy.
• Tuck the loose ends under the crossed laces or into the top of the boot so they cannot snag.

Lacing for common foot shapes

• High arches or high instep: window lacing over the highest point, and slightly looser mid-foot lacing.
• Wide forefoot: toe-relief lacing, or parallel (straight) lacing over the forefoot, which spreads pressure more evenly.
• Narrow foot or low volume: pull the forefoot snug, add surgeon’s knots between eyelets, and use a heel lock. A thicker sock or a volume-adjusting insole can also help; see our guide to insoles for trekking shoes.
• Bunions or sensitive spots on the side of the foot: loosen the eyelets nearest the spot and lock above and below with surgeon’s knots.
• Pressure above the ankle, at the cuff: leave the top hooks unused or take the lace over (rather than around) the final hooks before tying.

Blister quick fixes with your laces

Blisters are a sign of movement or pressure. Stop as soon as you feel a hot spot, take your boot off, and deal with it before it becomes a blister.

• Hot spot on the heel: cover it with tape or a blister dressing, then re-lace with a heel lock.
• Hot spot on the top of the foot: check for a lace crossing directly over the spot and open a window.
• Hot spots on the toes: descending? Tighten the lower laces and add a heel lock. Trim your toenails before the trek too.
• Pressure from the tongue: straighten it so it sits centrally and its padding lies flat before you lace.

A small blister kit belongs in every daypack. Our trek packing checklist lists what to carry.

Lace care, spares and replacement

Laces take a lot of wear from hooks and grit, and a snapped lace halfway through a trek is a real nuisance.

• Inspect before every trip. Look for fraying where the lace runs through hooks and at the tips (aglets). Replace any lace that is fuzzy or thin in places.
• Carry a spare pair on multi-day treks. They weigh almost nothing and double as a cord for repairs or a washing line.
• Match the original. Replace laces with the same shape (round, oval or flat) and the same length as the ones that came with the boot. Round laces generally run more smoothly through hooks; flat laces grip better in eyelets.
• Clean them with the boots. Remove laces before washing your boots, rinse off grit (which wears both lace and eyelets) and let them dry naturally. See how to clean trekking boots.
• Emergency fix: if a lace snaps, tie the two pieces with a reef knot and skip an eyelet, or use a length of cord until you can replace it.

Lacing for a Nepal trek

Treks in Nepal combine long, steep stone staircases with multi-hour descents, so lacing makes a noticeable difference. On a route like the Annapurna Base Camp trek, a single day can involve several hundred metres of climbing and descending on stone steps. On the Everest Base Camp trek, the days are longer at altitude, and feet can swell slightly as the trek goes on.

• Break your boots in for several weeks before you fly, and practise each lacing technique at home so you can do it with cold hands.
• Re-lace each morning, and again before any big descent.
• Expect to loosen the forefoot slightly as the trek progresses and your feet adapt.
• Pack spare laces and blister plasters; see our Everest Base Camp packing list.

Next step

Spend ten minutes today trying the heel lock and a window on your own boots, then take them on a hilly walk. Once your lacing is sorted, the next things to get right are fitness and kit. Read our guide on how hard the Everest Base Camp trek really is, or start planning your trek with us.

Frequently asked questions

How tight should hiking boots be laced?

Snug but not tight. The boot should hold your heel without lifting, and you should still be able to slide a finger under the laces with a little effort. Numbness or tingling in the toes, or an ache across the top of the foot, means the laces are too tight.

What is the best way to lace hiking boots to stop heel slip?

Use a heel lock. Lace normally to the second-to-top hooks, run each lace straight up to the top hook on the same side to make a loop, cross the laces, feed them under the opposite loops and pull down. A surgeon’s knot at the ankle bend also helps.

How should I lace boots for going downhill?

Tighten the lower and ankle laces firmly before you start the descent and add a heel lock. This stops your foot sliding forward and your toes hitting the front of the boot, which causes bruised toenails.

Should I loosen my boots for going uphill?

Slightly, at the ankle. Keep the forefoot snug but loosen the top hooks a little so your ankle can flex forward. This reduces pressure on the shin and Achilles on long climbs. Re-tighten before you go down again.

Why do my hiking boot laces keep coming undone?

The most common reason is a granny knot, where both halves of the knot are tied in the same direction. If your bow sits vertically rather than across the boot, start the knot the other way round. A double bow or a surgeon’s knot at the base also helps.

What is window lacing used for?

Window (or box) lacing relieves pressure on a specific spot on the top of the foot, such as a high arch, a prominent bone or a swollen area. You skip the crossing over that spot by running the laces straight up the sides.

Should hiking boot laces be round or flat?

Replace like with like. Round laces tend to run smoothly through hooks and are common on hiking boots, while flat laces grip well in eyelets. Match the length and shape of the laces that came with your boots.

How often should I replace boot laces?

Whenever they start to fray, thin out or lose their tips. Check them before every trek and carry a spare pair on multi-day trips, especially in remote areas where you cannot easily buy replacements.
