Eh, I used these for running in snow one time with my dog. It was the Polar Trex. I had the proper fit and everything but it had fallen off somewhere between 3 and 4 miles in. Never found it either. Quite a waste considering their are not cheap.I realise this is old thread but I was also wondering how these boots hold up and stay on. I grabbed Molly "Mutt-Luks" and they are great for staying on but after a season and a half they turn around on her feet.
The "ruff wear" brand looks like they would stay on properly.
