Thought I'd give those of you interested an update. I've had them a week now and worn them for 3 full days at work 2 of them in a row. I've had no blisters and the ankle soreness I had last week has gone (think I may have had the laces too tight!!!!). The weather has been pretty icy here today. We had rain late yesterday which froze overnight and then snow on top of that this morning!!!! I made it to and from work unscathed, apart from a minor skid on a frozen puddle but I think nothing would have kept traction on that!! I am over the moon with them and they are totally worth the £120 price tag, I've had loads of positive comments on them and my feet are lovely and warm with only 2 thin pairs of socks x
