Wooccoli sandals have an anatomically designed footbed that cups the heel, and has very pleasant arch support. The sandals have five "flex zones" that allows shoe to move naturally with your foot as you walk. A slight rocker at the heel and forefoot accentuates arch support and promotes a smooth, rolling gait. Natural materials and soft, vegetable-tanned leather uppers make these shoes healthy and hypo-allergenic, with no harsh chemicals used in the tanning process. The poplar footbed is coated with beeswax to prevent sweat from soaking into the shoes.
