With added stretch and a simple-to-use lace-locking mechanism for slip-on-and-off ease, the Sof Sole® Reflective Performance Laces go above and beyond the limited functions of traditional laces. Locking mechanism allows quick adjustments to lace tension, allowing you slip into and out of your shoes fast. To use, slide the locking mechanism onto the two ends of the lace and depress the button to slide the lace in. Pull the lace through the locking mechanism to the desired lace tension in the shoe. Release the button to lock in place. Use a match to heat the cut lace to keep tips from fraying. Laces stretch to reduce pinching and pressure points that can be caused by ordinary laces. Reflective fabric adds safety on the roads in low-light conditions. One size fits most. Imported. Colors: Black, Grey.
