The StrideX Ultra was developed in close collaboration with competitive road runners who demand speed without sacrificing the cushioning needed for long-distance training. The engineered knit upper wraps the foot like a sock, adapting to the contours of your foot without hot spots, while reinforced zones at the heel counter and midfoot provide structure and lockdown under load.

The FlowFoam midsole compound returns 68% of energy input per step — compared to the 52% industry average — meaning less leg fatigue over the final kilometres of a long run. An embedded carbon-fibre torsion shank in the forefoot reduces lateral flex, directing propulsive force directly forward through the toe-off phase.

The bi-density outsole splits into two hardness zones: a softer heel compound absorbs initial ground contact, while a harder forefoot compound provides grip and durability through push-off. The multi-directional sipe pattern grips wet pavement without adding weight.
