Thanks Clayton, I am prepared to have to buy another set as i think these may just not fit properly so thanks for the recommendation, good to know what definitely works. Also, you must be the only other person I know of that has a pair of these boots
Andy, I'll get some pictures later tonight/tomorrow. They appeared to be coming off at the front but can't say 100% as i was concentrating on getting a good grip on the ice axe in case they fell off. I suspect the front bar that attaches to the boot is not quite high enough so doesn't secure properly above the sole, causing it to slip off when front pointing.
