In reply to Removed UserMishel:
For the iowas, will they take a strap on crampon? Probably initially, but they dont seem to be designed for stiffness so it will not be safe and it will probably come off.
Winter climbing where? in the UK? Walking or ice/mixed?
I have managed in Trango's up to that altitude but it was about as risky as i would go.
If you want to save money go to a shop try all mountaineering specific boots that fit you and the climb then look for the pair second hand.
