These sandals are awesome if you work outdoors like landscaping. So tired of finding socks to wear with my heavy work shoes. Only thing I dislike is the limited Velcro to tighten ankle. I solved the problem by using epoxy to lengthen the Velcro straps around the back of the strap around the Achilles’ tendon. If in future models the company can lengthen the Velcro the sandals will be perfect!
