Please allow 12-14 business days for these to ship to you. These are a best seller every time we run them, because they are so good. I get compliments every time I wear mine. These high-quality flat soles are made from a vegan-friendly highly durable rubber. The stunningly woven stretch-to-fit straps are made from premium nylon designed to reduce rubbing and blisters. Compliment any summer look, from a formal dressy outfit to casual boho beach chic. Size chart pictured.
