Taking cues from it's breakthrough little brother, the Tech 1-Z, the latest Alpinestars Supermono racing shoe has been engineered to offer the ultimate performance driving experience. The ultra lightweight shoes feature Alpinestars' "sock" construction for, you guessed it, a sock-like fit. The contoured, sculpted shape perfectly adapts to the lines of your feet, while a minimalistic construction provides lightweight, fuss-free performance. Finally, The unique closure system uses a single large Velcro strap combined with an elasticated gusset that closes across the instep, creating an extremely secure and ergonomic fit, while greatly reducing weight.
