The one thing I was not impressed with is the sharpness of the hooks. This is an awesome setup and something that is going to last for a long time. Much better than I anticipated, they feel so sturdy not like the kind that tangles every time you take them on and off. It runs one size too small. Les encantaron. No glue, no stitching, nothing. The sandals do not look like they are orthotic, at all. It will change your life and most people will wonder why Apple did not think of it sooner. For approximately $20, I got a pair of noisy comfortable slippers. I received it today.
