Lightweight, highly cushioned and with a monster grip, the speedcross 3 is unlike any other shoe. - Upper Construction: Feather Construction: A construction that extends the upper material over the midsole, to create a super-precise wrap of the foot and improve the feel. - Upper Construction: Sensifit : SensiFit cradles the foot from the midsole to the lacing system, providing a secure, snug, and virtually customized fit all around the foot. - Upper Construction: Protective Mudguard: A wrap of leather, synthetic or rubber around the base of the foot that protects the lateral and medial sides of the foot. - Outsole: Mud Contagrip : Built for maximum grip on loose, soft, rugged, and uneven surfaces, Mud Contagrip uses deep, sharp lugs made from a compound that focuses on adhesion. - Midsole: Lightweight Muscle: A light but cushy midsole compound.
