At the Foundation of every successful outdoor adventure lies a thoughtfully designed pair of footwear. Chaco has spent the last two decades creating footwear solutions that meet the needs of the most demanding outdoor enthusuasts. Founded in 1989, Chaco's vision was to create a high performance sandal that embodies great fit and excellent durability while taking into account the impacts our business may have on the environment. We use our Addstride technolodgy which ensures a supported comfortable and efficent stride in any activity and as a result have been awarded the seal of acceptance by the American Podiatric Medical Association (APMA). In a majority of our products a continious pull through strap with an adjustable buckle confirm to any footshape and provide the best fit. Vibram is used on our sole units where neccessary to provide great traction and durability.
