The main factor that sets all Pantherella invisible socks apart from other 'invisible socks' is “fit” – they don’t slip off your heel and slide down your foot. Pantherella incorporates a specially designed non-silicon heel grip, a specially-designed arch grip, as well as a small percentage of Lycra in each sock in order to achieve this unrivalled 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 Pantherella we understand the importance of style, therefore offer a range of colourways and patterns to suit your personality.
