Castelli Incendio 15 Socks

Castelli Incendio 15 Socks. The Castelli Incendio 15 Socks are an ideal sock to wear while racing during cold weather. They are crafted from Primaloft material and wool, making them warm and insulated, but are thin enough to comfortably fit in to a summer shoe. The Incendio Socks are durable, with extra insulation in target areas, so they remain lightweight, yet warm. They also includes a 15cm cuff for guaranteed ankle coverage and increased calf coverage on cold days.
