The Icebugs I just bought are just coming, as are the snowy weather, so in practice I haven't gotten to try them yet. I fitted these over my old trail running sneakers (Salomon's XA 3D pro Mountain trail) and even though the front hook doesn't quite fit the laces of these, it seemed to stay in place very tightly. Sneaker size 38.5 and this "cover" size M. The really thin material of the protection is a bit questionable, only practice will show whether the ankles stay dry in the snow. At least I don't think it will hinder running in any way.
