What size do I order?
Z-CoiL Footwear generally runs true to size.
Width
Z-CoiL footwear is very ergonomically designed. Built with a rounded heel and raised arch we strive to support each contour on your feet. The toe box of Z-CoiL is wider than normal shoes and designed to prevent irritation in the toes and ball of the foot. In general, the ball of the foot is wide — however the width will vary slightly by style. Its important that you wear shoes that prevent cramping or squeezing of the toes. Tension on the toes can easily lead to bunions and disfigurement of the toes and ball of the feet. Its important to sets your toes free and allow them to spread out naturally with each step.
