The Alpinestars Tech 10 is the boot of choice for MXGP riders. Offering ultimate durability and protection for those who take motocross seriously. Every component of the Tech 10 has been continuously developed and tested in racing for uncompromised performance. The front and rear sliding blades help create a perfect anatomical fit and guarantee freedom of movement in the lateral direction while preventing unwanted rotation and stress. Extensive TPU protection on toes, foot, heel, ankle, calf and shin with extra hard compounds on the toe-box will absorb any impact from any direction for maximum protection. The innovative self-aligning buckles are constructed of heavy duty materials and are easily adjustable and replaceable. But the real eye catcher is on the inside of the boot. The Tech 10 comes with an inner ankle brace system for maximum protection of your feet. This brace gives greater impact protection of the ankle and progressively absorbs flex and rotation stress, reducing pressure and hyperextension injury to the lower leg joints. The Tech 10 truely is the best of the best.
