The ViLa sandal can actually be held securely to the foot by only the heel strap. The Velcro strap that is fastened around the ankle is just an additional security feature and so does not need to be pulled too tightly. In fact most of these Spanish style sandals do not have the Velcro strap. You can see our short movie on the about us page.
