Synthetic wing wraps around the heel for stability. Full bootie construction for a one-to-one fit. Injected Phylon unit sole for a lightweight, cushioned ride that's durable enough to double as the outsole. Injected unit sole is raised in areas for improved traction and cored out in lower-wear areas to reduce weight. Strategically placed rubber pods for grip and durability.
