Vionic VIO MOTION TECHNOLOGY: Vionic Shoes offer stability, cushioning, arch support, and flexibility. This technology helps correct pronation and promotes full body alignment. It is 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. If your comfortable shoes become wet, allow them to naturally dry.
