Vionic Elara Flat Sandal features VIO MOTION TECHNOLOGY, offering stability, cushioning, arch support, and flexibility. This technology helps correct pronation, promotes full-body alignment, and is designed to alleviate heel pain often caused by plantar fasciitis or achilles tendonitis. To maintain your Vionic shoes, we recommend wearing your new pair for a few hours to allow your feet to adapt to the new support. If needed, clean your shoes with a dry cotton cloth to wipe away dirt or dust. Do not submerge your supportive shoes in water. If they become wet, allow them to dry naturally.
