My question about this is how would you keep your binding loose without having the toe strap slip off? I have to tighten the hell out of mine to keep my cap strap on, and until I initially reconfigured the strap setup I was having major problems with them slipping off halfway down the hill. Not a problem now, but like I said I have to tighten them pretty well.
I think I would be more comfortable riding if they were a little looser, but I'd have to get around this issue first.
I think it was all in the ankle strap. His foot wasn't slipping forward, but he could lift his heel a lil bit out of the binding when strapped in.
