Have a few pairs of both the All weathers and Ascenders and they've been great training through end of summer and now into the winter months. Appreciate the initiatives for recycling your old socks and the earn per run fundraising approach as well.

Loved the socks, I used them for the first time doing 42km in the Lake District putting them through a right test. I will buy more.

I was a bit unsure as to how a pair of socks could help me running but how wrong was I. Having done a couple of 12k trail runs I find them very comfortable, my feet don’t overheat, yet keep them warm and no blisters. Will definitely use these socks for all my running now.
