Dial And Lace Specs

CS1

Flexible strength for low-power configurations. CS1 lace uses 49 strands of stainless steel wrapped in nylon to withstand abrasion to shed dirt, debris, and water.

Li2

Lightweight and low-profile, Li2 enables multidirectional adjustments for tightening and loosening at every turn, climb, and sprint. Built to last, the dial platform is engineered with unprecedented durability against impact, abrasion, dirt and debris.

"THE FEELING OF BEING DIALED IN IS SIMILAR TO THE FEELING I GET BEFORE A RACE — WHEN I TURN THE DIAL ON MY SHOES, I TRANSITION INTO THIS FOCUS MODE EVEN MORE.”
