The FUTURUM PROFORMANCE Merino Xtra Cool Socks are fantastic socks for warm days. The temperature-regulating effect of the merino wool keeps your feet pleasantly cool during your ride. The open structure makes the socks lighter and provides extra ventilation. The merino wool is self-cleaning and moisture-regulating, so you keep a comfortable and fresh feeling. Due to the addition of polyamide on the toes and the heel, the socks are extremely strong and durable. You can wear these socks in any season, but the special structure makes them extremely suitable for the hot summer days. It is an absolute must for fans of merino socks!
