18 adaptive Cloud elements and Helion™ superfoam combine with the re-engineered Speedboard™ to turn impact into acceleration. The curved heel unit means better hold, durability and comfort. Strategic taping and a new lacing configuration offer sure-footed freedom and support for high-speed goals.
The Swiss-engineered mesh upper is primed for race pace. Lightweight and reinforced to support tired feet, with zoned ventilation to let air flow through. An elastic strap keeps laces out of the way, and a new rubber compound in an advanced traction pattern offers superior grip on wet roads.
