ALPINESTARS Stella SMX-6 V3 Boots

The Alpinestars Stella SMX-6 V3 Boots are engineered for women riders who want race-level performance paired with everyday versatility. Designed with a dedicated female fit, they deliver a precise, supportive feel that enhances control on the bike while remaining comfortable for walking off it.

Built using Alpinestars’ race-inspired technology and protective materials, these boots balance flexibility, protection, and performance for both track days and street riding. A newly redesigned upper is precision-engineered to follow the natural contours of the foot for improved ergonomics and reduced fatigue, while strategic flex zones help the boot move naturally with the rider for a streamlined profile and a better connection to the bike.
