The Tech 10 is lighter, a result of Alpinestars technicians studying all the boot components and their connections – how the boot comes together. A re-design of every single one of those components has been undertaken to reduce volume and weight.New material composites have been created that are lighter in weight and more durable to ensure they hold up to the rigors of off-road riding. The new, cold-forged, aluminum buckles are a result with an easier to operate, more durable and self-aligning closure that offer a positive hold across the upper surfaces of the boot.The result has yielded over 400 grams (almost 1lb) in weight reduction for the new Tech 10.
