VIONIC VIO MOTION TECHNOLOGY: Vionic Shoes offer stability cushioning arch support and flexibility. The technology helps correct pronation and promotes full-body alignment and its designed to help alleviate heel pain often caused by plantar fasciitis or achilles tendonitis. MAINTAINING YOUR VIONIC SHOES: We recommend wearing your new pair for a few hours to allow your feet to adapt to the new support. To clean your shoes if needed use a dry cotton cloth to wipe away dirt or dust. Do not submerge your supportive shoes in water and if your comfortable shoes become wet have them naturally dry.
