Charnos Footsies with Heel Grip are specifically designed to provide comfort and prevent slipping or sliding inside shoes, thanks to their heel grip feature. The heel grip is a special silicone or rubberized material incorporated into the inner heel area of the footsie. It helps keep the socks in place and prevents them from slipping off your feet while wearing them with shoes. The grip creates a friction between the socks and your heels, reducing the chances of your socks bunching up or coming off during movement. Charnos Footsies with Heel Grip are often used with low-cut or open-toe shoes, pumps, ballet flats, or any other footwear where traditional socks might be too visible or uncomfortable. They provide a minimal coverage, usually covering only the toes, so they are a great alternative to wearing regular socks, especially in warmer weather or for dressier occasions.Low Cut Sanitized Actifresh 2 pairs per pack Handwash only Made in China
