The Tanza Leather sports sandal features a three-point strap adjustment system for fine tuning the fit & a nylon shank to provide the much needed support over undulating & sometimes unsure terrain. You can rest at ease knowing your feet are stable & in control. Spider Original Rubber keeps you stuck to the rock, in or out of the water & the open toe construction allows easier water drainage & doesnt allow water to pool underfoot. Waterproof Nubuck leather uppers combined with Tevas Mush topsole bring the comfort & luxury of their flip flops to this multipurpose sports sandal. Comfort is further enhanced by the heel Shoc Pad, a soft shock absorbing material is sandwiched into the midsole under your heel to absorb impact shock. & if your feet dont smell like roses, they have bolted on the Microban Zinc based anti-microbial treatment to protect against the build up of nasty pongy bacteria. Finally, just so we are all on the same page, its Teva (teh-vah, not tee-vah). Imagine a cockney trying to say tether & you are basically there. It would make the creator very happy if we all said it correctly.
