In reply to UKC/UKH Gear:
I've got a pair of these and I think they're ace.
I'd agree with pretty much all of the review, save for the walking bit, I don't find them clumpy to walk in at all and regarding the ankle support, there's lots of research out there to shoe the ankle protection on boots doesn't do much to prevent ankle injuries.
They really are an amazing weight, especially considering their warmth, my only concern is the sole wear, my toe area has lost it's edge quite quickly too.
