Alpinestars Stella Faster 4 Shoes

Drawing on decades of R&D experience at the highest levels of motorsports, Alpinestars incorporates cutting-edge performance innovations into the Stella Faster 4 shoes. The shoes' seamless knitted construction ensures exceptional lightness and breathability, while delivering class-leading protection both inside and out.
