In reply to Cameron94:
All my friends who climb ice have this. I did this to my first pair and it's nothing to do with the heat, it's kicking into the ice. If you climb ice as opposed to mixed sou will be kicking your front points in and will not be able to help the toe box getting bashed as the ice is never uniform. Basically the toe box isn't strong enough, climb ice = collapsed toe box.
I sent my first pair back to mountain boot company and got a refund, it was when they first came out. Every pair I see on ice climbers have this, from guides to weekenders, I'm surprised it doesn't get mentioned that much but I put it down to not much ice action in the UK and the relatively few days people get out overall.
