What the title says, really. Did a lot of walking in ski boots last year which killed my calves - of which I was reminded in LDA a couple of weeks ago on the horrendous trips up to the glacier... I've heard good things about cat tracks, but they seem to be more to protect your boot sole than to allow you to walk properly - the Walk EZ things seem to make ski boots more like MBTs. So, has anyone tried them and what do you think? I'm seriously tempted to order them from Father Christmas but will need to get my backside in gear pronto to get them from the US in time for Xmas
