“Easy purchase of a wonderful product. A little worried that the product's design and size were slightly different from the original 2 pairs gifted to me. Spenco Women's Supreme Slide Mule does not disappoint. I'm very happy with this product. Delivery was on time and as per the instructions. I will likely purchase this product again.”
