Orthaheel technology is biomechanically designed to support your arches and heels for all-day comfort. Great for those with plantar fasciitis heel stress, the Tide II's built-in orthotics have been shown to reduce heel pain in a peer-reviewed clinical study. Additionally, the lightweight, flexible, medium-density EVA midsole absorbs shock and reduces stress, while the TPR rubber outsole provides traction. A simple woven and leather upper strap and toe post ensure your sandals stay put. American Podiatric Medical Association seal of approval. Heel Height: 1"
