X300 Series-A series favored by many top athletes

This X300 series has the highest elasticity in the XTENEX series, eliminating the gap between the foot and shoes and achieving the best fit. As a result, it is favored by Olympic athletes, professional athletes, and amateur athletes who demand high athletic performance.

The X-series features an ergonomically optimal design for a comfortable fit without tying semi-permanently, making it an indispensable item for triathletes.


The installation method of the XTENEX series is as follows.

Stretch the laces through the shoe holes (which reduces the size of the knots), select the desired number of knots between the shoe holes, and set them apart. Repeat this process between each shoe hole to fit.
