Our cool Mercerized Cotton "invisible" socks are becoming a SOXESSORY's favorite. The main factor that sets them apart from other "invisible socks" is "perfect fit" - they don't slip off your heel and slide down your foot. SOXESSORY incorporates a specially designed silicon heel grip, a specially-designed arch grip, as well as a small percentage of Polyamide in each sock in order to achieve this unrivaled fit. Secondly, they sit very low on the foot so remain totally discreet. This style of sock may be hidden away when wearing shoes, but here at SOXESSORY we understand the importance of style, therefore offer a range of colorways and patterns to suit your personality.
