Unique tubular construction reduces bunching and offers a fit that encourages breathability and reduces hot-spots.


Alpinestars ZX Series Socks are constructed from Alpinestars innovative Lenzing FR material - a natural viscose fiber that offers exceptional flame resistance and protection against heat transfer, while still being incredibly soft to the touch, and highly breathable. The unique ZX construction uses body-map patterns and is tubularly woven to reduce the amount of seams. This allows for reduced bunching in the shoes and a fit that encourages breathability and reduces hot-spots.
