These sandals are made for a narrower foot than the medium I usually wear.  It is comfortable, but the straps are at the limits of their Velcro straps.  As noted by other reviewers, the ankle strap is angled too high and consequently, bows a bit at its base.  Despite these flaws, the sandal was comfortable to wear right out of the box.  I would not buy them again because of the width issue, but will probably wear them a lot this summer.
