Why Lacing Technique Matters

Most climbers lace their shoes the same way they lace their trainers and never think about it again. That's a mistake. Climbing shoe lacing is a performance variable — the difference between a shoe that feels sloppy and one that feels locked in can often be solved entirely by changing how you lace, not by buying a new shoe.

Think about it this way: a climbing shoe is a precision tool. The rubber, the last shape, the rand tension — all of it is engineered to transmit force from your foot to the rock as efficiently as possible. But none of that engineering matters if the shoe isn't held securely against your foot. Lacing is the interface between your foot and the shoe, and getting it wrong undermines everything else.

The key variables lacing controls:

• Heel hold — how securely the heel cup grips your heel during heel hooks and overhanging moves
• Pressure distribution — how evenly the shoe wraps your foot, preventing hot spots and pain
• Toe box tension — how much the shoe compresses your toes, affecting sensitivity and comfort
• Midfoot lockdown — how stable the arch feels during edging and smearing

For lace-up climbing shoes like the Castiron Grip N23 and SWIFT, lacing technique is one of the most underutilised performance tools available to climbers at every level.

Basic Lacing: Getting the Foundation Right

Before getting into advanced techniques, the foundation matters. Most climbers make one of four basic lacing errors that undermine everything else:

The correct starting point: Thread the lace through the bottom eyelets and pull snug but not tight. Work upward, applying slightly more tension with each eyelet pair. The toe box should feel secure but not compressed. The ankle eyelets should feel locked in. A useful test: stand on your toes and push your heel back — if the heel cup moves, tighten the ankle eyelets.

Heel Lock (Surgeon's Knot)

The heel lock — also called the surgeon's knot or runner's loop — is the single most impactful lacing technique for climbers. It creates a secondary locking point at the ankle that prevents the lace from loosening during dynamic moves, heel hooks, and overhanging climbing.

Without a heel lock, the tension you apply when you tie your shoes gradually redistributes as you climb. Every dynamic move, every heel hook, every time you jam your foot into a crack — the lace tension shifts slightly. By the end of a long route at Stanage or Malham, your shoes can feel noticeably looser than when you started. The heel lock prevents this by creating a fixed point that the lace can't slip past.

How to tie a heel lock:

1. Lace normally through all eyelets up to the second-to-last pair
2. At the second-to-last eyelet pair, loop each lace back through its own eyelet to create a small loop on each side
3. Cross the laces through the loops on the opposite side
4. Pull tight — this creates a locking point that won't slip
5. Continue to the top eyelet and tie your standard knot

When to use it: Any time you experience heel slip during climbing. Particularly useful on overhanging routes, heel hooks, and when climbing in shoes that are slightly large. The N23's lace-up closure makes it ideal for heel lock technique.

Window Lacing for High-Volume Feet

Window lacing — also called gap lacing or skip lacing — relieves pressure over a specific part of the foot by skipping one or more eyelet pairs. This creates a "window" of reduced tension over a pressure point.

When to use it: High instep or high-volume foot that causes pain across the top of the foot, bone spurs or sensitive areas, or shoes that feel too tight across the midfoot but fit well everywhere else.

How to window lace:

1. Lace normally up to the eyelet pair just below the pressure point
2. Run the laces straight up (parallel, not crossing) to skip the pressure point eyelet pair
3. Resume normal cross-lacing above the skipped eyelets
4. Continue to the top and tie off normally

You can skip one or two eyelet pairs depending on how large the pressure-free zone needs to be. This technique can transform a shoe that feels unwearable into one that fits comfortably for a full session at The Climbing Works, The Castle, or your local wall.

Toe Box Pressure Relief

Climbing shoes are designed to fit snugly — but for some foot shapes, the toe box creates excessive pressure on specific toes. This is especially common with the big toe on asymmetric lasts like the N23.

Toe box lacing relief technique: Start lacing from the second eyelet pair rather than the first. Thread the lace end through the first eyelet from the outside in, creating a loop, then run the lace up to the second eyelet and continue normally. This reduces tension specifically at the toe box while maintaining normal tension through the midfoot and ankle — useful for climbers with sensitive big toes, bunions, or Morton's toe.

Zone Tightening for Different Terrain

One of the key advantages of lace-up shoes over velcro is the ability to adjust tension by zone. Different climbing terrain benefits from different tension profiles:

Practical application for UK climbers: lace tight with a heel lock for steep limestone at Malham or Gordale Scar. Lace looser at the toe for gritstone slab at Stanage or slate at Dinorwig. Adjust mid-session if the terrain changes — that's one of the key advantages of lace-up shoes over velcro.

Lace vs Velcro: When Lacing Matters Most

Velcro climbing shoes dominate the gym and bouldering scene because they're fast — on and off between problems in seconds. But lace-up shoes offer performance advantages that velcro can't match, particularly for outdoor climbing and longer routes.

Lacing for UK Rock Types

Gritstone (Stanage, Burbage, Froggatt, Curbar): Lace the toe box looser than you would for limestone — you want maximum rubber contact with the gritstone surface for friction and smearing. Medium-tight at the midfoot and ankle. Use the heel lock for overhanging gritstone problems.

Limestone (Malham, Gordale Scar, Pembroke, Wye Valley): Lace tighter overall, with a heel lock for any route above vertical. The N23's asymmetric last combined with a tight heel lock lacing gives you maximum precision on limestone pockets and edges.

Slate (Dinorwig, Rainbow Slab): Lace the toe box very loose — you want the rubber to deform and maximise contact with the smooth slate surface. The SWIFT's flat last is the better choice for slate, laced loose at the toe.

Crack climbing (gritstone, Pembroke sea cliffs): Lace loose throughout — tight lacing prevents the foot from conforming to the crack shape and reduces jamming effectiveness.

Frequently Asked Questions

What is the best lacing technique for climbing shoes?
The heel lock (surgeon's knot) is the single most impactful technique for most climbers. It prevents heel slip during dynamic moves and heel hooks. Combine it with zone tightening — looser at the toe, tighter at the ankle — for the best overall fit.

How tight should I lace my climbing shoes?
Tight enough that the shoe doesn't move on your foot, but not so tight that your foot goes numb. The toe box should feel snug but not painful. The ankle should feel locked in. If you lose sensation in your toes, loosen the bottom two eyelets.

What is window lacing for climbing shoes?
Window lacing skips one or more eyelet pairs to relieve pressure over a specific part of the foot. It's useful for climbers with high insteps, wide feet, or sensitive pressure points on the top of the foot.

Are lace-up climbing shoes better than velcro for UK outdoor climbing?
For UK outdoor climbing — gritstone, limestone, slate — lace-up shoes offer more precise fit adjustment and better heel hold. The N23 (lace) is the top pick for outdoor sport climbing. The PR23 (velcro) is better for gym sessions and bouldering.

How should I lace my climbing shoes for gritstone?
Lace the toe box looser than you would for limestone — you want maximum rubber contact with the gritstone surface for friction and smearing. Medium-tight at the midfoot and ankle. Use the heel lock for overhanging gritstone problems.

How should I lace my climbing shoes for slate?
Lace the toe box very loose for maximum rubber contact on polished slate. The SWIFT (£99) is the best Castiron Grip choice for Dinorwig and Rainbow Slab.

Does Castiron Grip ship to the UK?
