I could not wear them at all...I have a high instep and could not even get my foot into them plus the Velcro straps were not long enough to even close over my foot. Too short they needed to make them longer! I was so disappointed plus the foot bed is HARD PLASTIC so not at all what I wanted.  Sadly I have not been able to find any. I needed a men's size 6 they don't make them that small so tried the boys size and that was a bust!  I have a short wide foot with a high instep. I wear a mans E width size 6.  .  Women's sizes are all too narrow. I wear a women's size 38 in European sizing.  AND a DD width!  It is not manufacturer's fault. But I would NEVER buy a shoe that is HARD PLASTIC!
