The Bi Climasocks Marathon sock is a specific sock for the marathon, it will accompany you from training to competition. It is a thin and breathable double shank short sock designed for running. The friction causing ampules is between the 2 socks and not on the foot. Climasocks technology optimizes the performance of your waterproof and breathable membrane shoes.

We tested the Bi Climasocks Marathon socks in a 20km running session on the shores of Lake Annecy with Salomon Sonic Pro running shoes.

First we really appreciated the comfort of the sock, we feel no discomfort during the session, we focus on its performance. The thickness of the sock is relatively thin.

4 ventilation sectors for a better foot climatology

The great advantage of the Bi Climasocks Marathon is that it integrates a second skin in Coolmax inside the sock, so that the blisters are limited or even nil depending on the feet. It is a sock built against blisters.

Outer sock in hydrophobic and resistant Dryam microfibre polypropylene

Variable bi-m mail at the neck of the foot for better support.

Friends marathon runners we have a sock designed especially for you, your comfort.
