EUC Vionic Tortoise Shell Sandals Hilda 8 W Podiatrist Designed Toe post with metallic swirl disk detail, patent woven embossed patterned strap. Microfiber-wrapped EVA footbed and fabric liner. Durable rubber outsole with textured tread for good traction on a variety of surfaces. Podiatrist-designed, biomechanical orthotic footbed with Vio-Motion technology and a deep heel cup helps stabilise, support, and realign feet back to their natural position during ambulation. Helpful in relieving pain caused by faulty gait pattern such as over-pronation (flattened or collapsing arch). A complementary option to corrective orthoses for hot weather climates and seasons. Or to wind down at home and cool down achy, tired and for some, swelling of legs, ankle and feet. Great Vionic Sandals! 🌟🌟🌟🌟🌟
