This Waterpro runs fast wet or dry - a prime candidate for canyoneering as mesh upper drains automatically via ports in micro mesh upper and in antimicrobial footbed. Dynamic lacing system locks together a micro-mesh upper and supportive synthetic leather strapping. Air Cushion midsole for amphibious ventures includes Q-Form® stride alignment for women. New Vibram® Waterpro Plus™ sole has softened chevrons for land heavy siping for wet surfaces.
