Bought a half size over in wide and my mom still found it too tight.

And more importantly the strap come loose too easily. They have very little surface to grip onto.  Most shoes that I've seen have Velcro straps that go across to the other side, go through a slit, and wrap back onto itself. These do not. There is a small surface on the other side and that's it.

The bottoms of the sole are nice and grippy.

Sorry but these have to go back.
