Wigwam Trail Trax Pro - Supplied by Ed & Phil Ltd
This is the king of socks, equally at home in the bogs of Dartmoor in the winter and in the searing heat of the Kalahari Desert. In the cold and wet the sock, because of its construction, will keep your feet warm. In the desert, because of its wicking ability, it will keep your feet dry and prevent blisters.
In less extreme environments you may not need such a good sock, however, as is the case with most things, quality works out cheaper in the long run. (Pun intended) Ed & Phil Ltd sells mostly to independent retail shops, but the company does have some of its great running gear available online.
