These are fall/winter ultra (long distance) socks with the "T2 Ultra Socks / Crew" stretched into high socks and some fabric changes (color: Khaki). *There are 3 colors available. - The length can be adjusted according to use and weather conditions. The slightly longer length allows you to choose two ways to wear them: high socks (pic.1) when you don't want to interfere with knee mobility, and knee-high socks (pic.2) when it is cold or you don't want to keep your knees cold. - Graphics featuring the T2 logo - "Arch Surport" to prevent the foot from falling off the ground during long-distance running (pic.6 / image in color: Black) - High cushioning performance with thicker sole (pic.6 / image in color: Black) - Airy, puffy polyester and shrink-resistant washable wool are used in the "Bound Wool" fabric for fall and winter. The result is a "washable poly wool sock" with excellent warmth retention, moisture absorption and quick-drying properties, as well as high pilling resistance to prevent pilling, making it ideal for trail running. - Optimized for fall and winter running by mapping different materials and knitting methods for each area. (1) Neck → Thick pile weave on the skin side of the shins, which are prone to injury on trails, and thin weave on the calf, which is hard to get winded by, to improve quick-drying and breathability. (pic.7, 8 / image in color: Black) Depending on the season or mountain area, plants can easily get caught in the pile on the shins, resulting in pilling or yarn sticking out. Please understand this beforehand. (2) Ankle → Highly durable nylon yarn was used for the talus area (ankle front), which is easily rubbed by the shoe tongue, and the T2 trademark (pic.9, 10 / image in color: Black) (3) Instep → The instep is made of mesh knitting to suppress steaminess of the thick toes and soles. (pic.10 / image in color: Black) - Same specifications as "T2 Ultra Socks / Crew" from the bottom of the foot to the T2 trademark. ［3 types of fabrics] (1) The main fabric is Dralon Cotton, a German acrylic fiber mixed with cotton. It is characterized by high sweat absorption and quick-drying properties, odor resistance, and a soft and supple touch. (2) The front side of the ankle, which is easily damaged by rubbing against the shoe tongue, is made of high-strength nylon. (3) The sole of the foot is made of a rough bouclé yarn that enhances cushioning and prevents shifting inside the shoe. - The mesh knitting is used for areas that require ventilation, the tuck knitting for arch support areas that require compression, and the 1×1 rib knitting for the upper part from the ankle to prevent over-tightening even if the foot is edematous after a long distance run. ---------------------------------- Color : Khaki Material : Polyester, Wool, Acrylic, Cotton, Nylon, etc. Size : M-L (25-27cm), S-M (23-25cm) Length : M-L/400mm, S-M/380mm ---------------------------------- *Designs and specifications are subject to change without notice due to product updates. *The colors in the images may appear different from the actual colors due to the shooting and display screen.
