Bought these sandals less than four months ago. The Velcro strip has totally separated from the strap on the left sandal and is starting to separate on the right, rendering them useless. I contacted the seller, Shoe Station, who said they were out of warranty and to contact the manufacturer. When I contacted Aetrex I was told there was nothing they could do because this seller did not have authority to sell their shoes! So I am left with a pair of useless sandals less than four months old that cost me over $66.00 with shipping. See the photos of the separation. I strongly advise against buying this product.
