SON-R Technology™ gives these amphibious shoes amazing stability and sensory feedback so your feet will be at their agile best on whatever surface your adventures take you. Their unique outsole/midsole design enhances proprioception (the unconscious perception of movement and spatial orientation), effectively giving you the ability to See With Your Feet™. Articulating outsole pods transfer information from say the deck of a boat or the ground to corresponding pods in the removable, interactive footbed to your feet. Hydro Grip™ rubber in the outsoles delivers maximum traction. Nylon and mesh uppers with internal drainage ports and anti-microbial linings dry quickly and minimize odor. Easy elasticized strap closure. Imported.
