NaturalFit™ · Fit & width

Tailor your fit

Technology

Built for the trail

Cushioning for long descents, low weight for the climbs and a locked-in fit for technical ground.

Cushioned

6mm drop and a 34mm heel, 28mm forefoot stack (midsole only). Enough cushioning to absorb rocky descents and long downhill sections — while keeping the foot close enough to the ground to stay stable on uneven terrain.

// 6mm drop · 34mm heel, 28mm forefoot

Light

At 228g, it keeps your legs fresher over long distances. Supercritical TPEE foam absorbs impact and returns energy with every stride — from the first climb to the last kilometre.

// 228g · Supercritical TPEE

Secure

NaturalFit™ Standard last — the heel and midfoot lock in so the foot doesn't slide on off-camber ground, while the forefoot leaves room for the toes to splay on landing. Secure footing on technical trails.
