Conventional sock wisdom dictates that you can either have padding for protection and comfort, or two layers for reduced friction.  Padded socks are thick, double layer socks are thin.

The 1000 Mile Fusion Sock breaks that mould with innovative design and material technology to provide a sock that offers everything:

BLISTER FREE GUARANTEE, together with padded comfort and protection.

Now available in an ankle length version for those who prefer a shorter sock: 1000 Mile Fusion Anklet Sock.
