Made of a Merino blend, these socks are very versatil: wear as is in everyday life, or together with thin liners. The bottom, toe area, heel and Achilles tendon areas have extra cushion. The shaft and top of the foot are made with a thinner, highly breathable material weight. The double rib knit at the cuff helps keep the socks in check. - Suitable for warm and cool weather - for cold winter days we recommend thicker socks - 31% Merino wool, 9% wool, 35% Nylon, 24% Endurofil polypropylene, 1% elastane - Sizes: - M = 40 - 43 - L = 44 - 47 - XL = 48+ - Material and manufacturing guarantee: 5 years - Shaft length 21 cm above the heel - Fine wash at 40ºC without fabric softener
