The main idea behind the T-Free socks is to combine an already highly technical Sidas sock with a separate compartment for the big toe. The role of the big toe in running is significant in terms of balance, step direction, and the push-off phase. Among those involved in the design of the sock model is Jonathan Albon. The knit varies in thickness at different points - areas that are not prone to intense wear have a more breathable knit than others. Compared to running socks designed for even surfaces, Sidas trail running socks have additional padding in the ankle, toe area, and heel. - Reflective stripe - Light ankle support - Areas made of very gripping material prevent the sock from slipping in relation to the shoe - Polygiene odor control treatment - Made in Europe - 53% polyamide - 32% multifilament polyamide - 9% silicone - 5% elastane - 1% reflective fiber - Machine wash at 30ºC, inside out, do not use bleach or fabric softeners
