The Crossfire 3 SRS is the new standard in MX boots. The most important new feature is the adjustable calf system accompanied by a slim design that includes a double adjustment for riders with large calves or knee brace systems. Compared with the Crossfire 2 SRS, the entire sole system has been redesigned. The new sole “boat” features a more cupped and thicker design so the rider’s foot rests deeper into the sole system. This change gives more engagement between the boots upper and sole in manufacturing which will extend the boots lifespan. This change also creates a firmer sole than any other Crossfire boot. Along with an all-new ankle pivot system designed to provide the best possible protection, the new Crossfire 3 SRS is the new standard for Motocross boots!
