The Tirra Sandal is designed specifically for a woman's foot to provide unmatched comfort and performance in the water. With its unmistakably feminine strap configuration and multiple adjustment options for a secure fit, the Tirra can tackle any obstacle with ladylike grace - just like you! Made of water-friendly neoprene foam with a stretch mesh lining for quick drying and a Microban zinc-based antimicrobial treatment to help reduce odor. Molded nylon shank adds stability and support. A polyurethane/EVA Shoc Pad in the heel cup absorbs shock and provides greater spring with each forefoot push-off. The Spider Original nonmarking rubber outsole provides uncompromising grip in wet environments, and its water-channeling lug pattern helps to maintain solid footing. Imported.
