I have not used Axis 12's but my companion on a 3 day Porkies trip a year ago used them and had troubles with the binding straps slipping due to ice accumulation starting day 2 and worsening on day 3. Conditions were day 1 high 20's temp, day 2 temp 20 to high 20's, day 3 temp 10 to mid 20's. Snow depths were possibly similar to what Stephen experienced last weekend, up to 40" and fluffy. Our feet were buried in snow that spilled in on top of the snowshoes on every step (except when we were within a mile or two of park HQ and the trail was well used).
