Shear reduction linings prevent skin abrasion during repeated friction events.

Go long in the TRAILFLY? MAX. We??ve taken our popular TRAILFLY? shoe and maxed it out with a generous slab of new FLYSPEED? PRO foam for a comfortably cushioned yet naturally responsive ride ?C perfect for long distances and ultras over hard-packed trails.

The new supercritical, nitrogen-infused EVA foam is our highest performing to date. It??s super-lightweight, while giving both greater comfort and superior energy return. We??ve put 24mm of it in the heel and 18mm in the forefoot. This combines a 6mm deep, energy-popping BOOMERANG footbed for a bouncy feel that retains stability underfoot and plenty of agile ground feel.

The natural, foot-shaped design of the shoe ?C combined with the upper??s MET-CRADLE overlays ?C work to lock in at the heel and midfoot for confidence-boosting hold. The shape then widens at the toes, allowing them to spread, perform naturally, and increase that feeling of underfoot control, even on technical trails.

Hard-wearing, tacky rubber infused with the world??s strongest material ?C Graphene ?C covers the outsole. The 4mm long multi-directional lugs not only cut through loose trail and remain super-durable but also give improved grip in wet conditions. Underfoot flex grooves further enhance the agile, natural feel.
