Crumple Zone Configuration
HydroFlow® | Dynamic viscous fluid units for heel and forefoot
enhance midsole cushioning—attenuating shock with industry-leading dampening and comfort.
S-257™ Cushsole | Durable, energy-efficient midsole compound
utilized as an insole board for even more cushioning and flexibility.
Diagonal Rollbar (DRB™) | A high density post at the medial arch
is engineered for pronation control and creates a smoother transition from the midstance phase into the propulsion phase.
DRB Accel™ | Enhances tunable torsion of the midfoot. Shank-like
thermoplastic devices vary from single units of a set modulus, to
dual unit versions of varied modulus (one tuned with higher stiffness
for medial support, the lateral side less stiff to smooth the ride).
Engineered Stable-Pod Configuration | Midsole and outsole components are engineered to set the foot up in an efficient, balanced
position from heel strike to toe-off, offering maximum stability
and responsiveness.
