XTENEX Accu-Fit Adjustable Compression Laces are the ultimate shoelace you don't have to tie. Xtenex Xlaces feature enlarged (auto-blocking) knots that can be reduced in size by stretching the lace apart. Release the tension back to the lace and the knots will reappear to set your custom fit eyelet to eyelet.
