My SIDI boots are in new condition; I used them twice. These are fantastic boots! I had to give up motocross due to getting in a car accident and messing up my back. I liked them, because you can replace different parts. Text me if interested. The Sidi Crossfire 3 SRS boots serve that reputation well. Completely redesigned from head to toe, the boots highlight Sidi’s unique ability to pair innovation with tradition. Many of the features that made the Crossfire 2 SRS boots so popular can be found in the 3s, just carefully refined with an emphasis on protection, fitment, comfort, and convenience for the everyday rider, weekend warrior, and everyone else in between. Protection Ankle pivot system Rigid, shock resistant heel Hard TPU and protective plastic A major protective component of the Crossfire 3 SRS boots is their all-new ankle pivot system. Featuring a "hyperextension block," the technology prevents hyperextension of the foot and ankle, limiting rider’s risk of injury and instilling a sense of safety. The reformed heel is noteworthy as well, boasting a design that keeps the foot planted in the boot and resistant to twisting. These notable features, along with the other protective systems in the boot, are all shrouded in hard TPU and protective plastic for an extra layer of insurance.
