The first ever climbing foot powder meant to be used BEFORE you climb. Guaranteed to stop sweat and stench before they form. Our shoe chalk is designed specifically for climbers - it helps reduce sliding and prevents blisters from forming. Coat the entire shoe in powder to maximize effect and comfort. P.S. They work wonders for breaking into new shoes! Each packet contains roughly 2 months of usage assuming 3x sessions per week. Subscriptions require a min. of 2 refills before cancellation.
