Defying the force of gravity with extreme cushioning that weighs less than nine ounces, Easy Spirit delivers dynamic innovation with Anti-Gravity technology. The key formula is nitrogen bubbles in the footbed and dual-density midsole. The remarkable Elon midsole is molded for firm support, yet soft enough to absorb impact. Natural walking is promoted via a beveled heel and a rocker designed outsole that naturally "rocks" the foot from heel to toe for smooth steps. This suede sneaker features a hook-and-loop strap. And the rubber outsole gives plenty of traction and flexibility, while jersey lining pampers feet and reduces irritation.
