it looks like they can perforate the shoes and pinch your feet
Nails are too long, it looks like they can perforate the shoes and pinch your feet.  I bought to use on flat shoes, but with those long nails I did not dare to use it, I was scared they were going to hurt my feet.  The patch is too high too, it'll  create really bad unbalance on your feet.
