These are terrible. I purchased four pairs of these shoes between myself and friends and had the same problem - the crampons bent the first time out and the snow stuck to them so badly that huge balls were created and we couldn't walk more than five steps without our ankles rolling. I live in Alberta, where the snow is dry and fluffy and it still happens. Customer service was useless, suggesting I try wax on the crampons, which I did to no avail. They haven't answered any other emails. DO NOT BUY THESE SNOW SHOES! They are a good price, but a great example of you get what you pay for unfortunately. read full review »
