XTENEX® XF-Series features a Flat Lace with a self-forming TAPERED Flat Knot design, making XF laces the easiest to lace-up and adjust in the Xtenex Accu-Fit Lace Series. TAPERED Flat Knot design blocks the lace from involuntary lace migration and holds a custom ergonomic fit to your feet. XF offers a more traditional lacing experience but delivers the functionality and benefits of Accu-Fit lace technology by adjusting the compression fit at each eyelet. The XF-Series offers a superior reliable fit compared to the typical “bungee/elastic” laces.
