Flexible and lightweight, the KEEN Men's SOLR Sandals are an excellent choice for boating and other water sports. Zonal siping on rubber outsoles give you added traction on wet surfaces, while foam cushioning in the midsole and footbed keep you comfortably on your toes. The rubber is non-marking, so it won't streak your boat or other watercraft, and the upper is made of thermoplastic polyurethane to resist abrasion and add durability. This rugged water sandal is easy to keep looking great because it's also machine washable.
