Snowshoe help needed

Hi everyone,<br><br>
I've been going out more and more on my snowshoes. I love 'em! I have two problems though. The first is that I find that my foot tends to rotate within the binding, even though I tighten it as much as I comfortably can. Is this normal or are they just crappy bindings? The model is the Tubbs 10k (see attached pic). I was thinking that maybe some type of grippy material on the foot pad part of the binding may prevent this (like grip tape for skate boards). Any thoughts?<br><br>
The other problem I have is when the snowshoe occasionally hits my ankle....My god that hurts!!! Does anyone wear any kind of ankle protection to prevent this? ...or do people just use a wide stance (a la Senator Craig).<br><br>
Thanks!<br><br>
