these shoes absolutely stank.  i coudln't even wear them for a few minutes - as soon as i took a step, the velcro would detach!  shoddily designed, that strap.  and the shoes weren't going to stay on my feet without the strap.  i have never thought of myself as someone with insanely high arches, but there ya go.  shoes were worthless.  i coudln't return them (got them elsewhere for really cheap!), so they're going to goodwill.  perhaps someone out there can make them work.
