The Tide Toe Post Sandal is sure to have a comfortable fit with its soft woven toe post and foam-lined strap. The biomechanical Tri-planar Motion Control footbed with deep heel cup was designed by podiastrists to help stabilize, support and realign the feet back to their natural position. This sandal will reduce stress on your feet, ankles and knees with its lightweight, flexible medium-density EVA midsole that absorbs shock. The TPR outsole with patterned tread offers increased durability and traction.
