The Castelli Premio Women's Socks live up to their name by incorporating Castelli’s best technologies, conceived to keep your feet comfortable and healthy throughout your ride.They are made with 200-needle construction, a technique that creates extra stretch for a great fit, with multiple-structure knit ensuring that each part of the sock is the right thickness, with the right qualities to do its job well.For instance, a compressive midfoot support band reinforces the arch of the foot, taking the pressure off your muscles, while a thicker section at the ball of the foot offers cushioning in the area cyclists put most pressure on. At the same time, asymmetrical construction ensures both feet enjoy the same advantages.The sock’s versatility is further enhanced by a reflective tab at the back, which helps optimise your night-time visibility, and the use of yarns enriched with antibacterial silver ions, which keep your feet smelling fresh. These really are meticulously designed, premium socks.Features:Multiple structure knit means best performance in every area200-needle construction adds stretchAsymmetrical construction mirrors the shape of the footSupportive band at midfoot, with cushioning pad at ballConstructed from Q Skin yarns with antimicrobial silver ionsReflective tab at centre back
