It is a true double bi-material sock, a combination of 2 technologies, Climasoks and Bi-socks, which prevents and stops the formation of blisters because friction is exerted between the two socks, and not between the skin and the sock. Cutting-edge stitching made in ultra-flat, interlocking knit.

The strong point of the BI-CLIMASOCKS system is the use of different fibres between the 2 socks, providing an adapted response in terms of breathability, protection, moisture wicking, warmth, softness and perfect support. Some models incorporate a fine loop reinforcement positioned between the two socks from the top of the toes to the achilles heel, providing even more protection and comfort for the wearer.

Double bi-material sock

- Protects and prevents the formation of friction blisters because the friction is between the 2 socks and not on the foot.

- Provides hyper ventilation thanks to the micro perforation on and under the foot which allows air circulation up to 251% more than a conventional sock: with each step the pressure exerted on the sole evacuates humid air and then ventilates dry air.
