When she tries to wear them down the slide, the heel of the shoe/sock is also anti-slip. Not much support or cushion on these sandals I would not recommend them I just use them as house slippers because they really don’t have enough cushion to walk around outside or for any amount of time You cant even walk 3 steps without the Velcro coming loose and you step right out of the slide. After a lot of wear, my toes tend to slide forward a little off the front edge because of the wedge shape and that is uncomfortable after a few hours.
