Goldwin ski socks. I bought these two seasons ago intending to use them for winter mountaineering and backcountry skiing, but I never ended up using them. I hope someone can use them. Retail price is about 4000 yen. Below is the official description: High socks for winter sports that combine the functionality of merino wool and C3fit's unique support structure. A mid-thickness type with a comfortable fit that emphasizes heat retention, recommended for beginners to intermediate users. Acrylic and wool are used as the base materials, and the pile structure provides high heat retention. It has the moisture-absorbing and releasing properties of wool, making it warm but less prone to stuffiness. The pile structure is mainly for cushioning, which reduces the pressure of the boots. By not using a pile structure only on the side lines of the leg and foot parts, breathability and fit are improved. This reduces stuffiness inside the socks and prevents the fabric from bunching up inside the boots. The cross taping structure is used on the soles of the feet to support the inner and outer longitudinal arches. By supporting and preventing the arches from collapsing, it not only absorbs the impact on the legs, but also the arch of the foot acts as a spring to provide propulsion.
