The sandals were uncomfortable for the first 4-5 wears. The back strap is very stiff and it rubbed against my heel, causing really bad blisters. The worst part, however, is that in less than a month of wearing, one of the straps has come out and both soles are coming apart. This indicates incredibly poor quality, even though this product is more expensive than Pons, the comparable brand. I am very disappointed by the quality of this product given the price. Will not purchase this brand or from this seller again.
