X-Series features round self-forming, FLARED Knots, optimally designed to block-in a semi-permanent, no-tie fitting.
X300 series elastic shoelaces service eyelet diameter sizes from (3.5 to 4.5mm). The unique design of the Xtenex lacing system solves the problem of lace migration. Xtenex laces have an elastic core and a series of knots along the entire length of the lace at consistent length intervals.
X300 laces are a favorite in athletic shoes, hybrid golf shoes, casual shoes, senior shoes, children�s shoes and almost ANY shoe type imaginable.
