The main idea of the T-Free socks is to combine an already highly technical Sidas sock with a separate big toe compartment. The role of the big toe in running is significant in terms of balance, steering the step, and the push-off phase. The sock design has involved contributions from, among others, Jonathan Albon. The knit is of different thicknesses in different areas - areas that are not susceptible to strong wear have a more breathable knit than others. The socks are relatively thin, offering potential for a great running feel when worn with well fitting shoes. - Reflective stripe - Light ankle support - The area made of a very gripping material prevents the sock from sliding relative to the shoe - Polygiene odor control treatment - Made in Europe - 90% polyamide - 5% elastane - 4% silicone - 1% reflective fiber - Machine wash at 30ºC, inside out, do not use bleach or fabric softeners
