XTENEX - X200 Neon Pink 20" (PATENTED) Adjustable Eyelet Blocking No Tie Elastic Shoe Laces for an Extreme Lock In Performance Fit

描述

XTENEX (indeXed-TENsioning-nEXus) is a worldwide patented elastic shoelace technology that produces adjustable tensioning between a shoes eyelets. XTENEX Laces have an elastic core and a series of knots along the entire length of the lace at consistent length intervals. Stretch the lace and the knots disappear, allowing you to thread the lace through the eyelets. Release the tension and the knots reappear. More knots between eyelets lessens the tension; fewer knots between eyelets increases tension.
