The flex insert, tongue and collar are made of one piece of Schoeller® stretch fabric coupled with a stretchy Gore-Tex® lining, for greater comfort and a more anatomical fit while a stretch gaiter on the cuff keeps out debris. A progressive lasting board better matches stiffness/flexibility to the length of the boot, while the original Helix rand offers greater protection from abrasion and rock impact as well as better grip and torsional stability.
