The Alpinestars SMX Plus motorcycle boots provide advanced protection, flexibility, and secure fit for sport and performance riders. Designed in black for a streamlined riding look, these boots are sized for US 9 / EU 43 and feature an advanced microfiber upper that helps reduce weight while delivering dependable abrasion resistance. The manufacturer part number and vendor part number are both 2221019-10-43.
Protection: Alpinestars Multi-Link Control system supports ankle articulation while limiting hyper-torsion, hyper-extension, and hyper-flexion. A contoured high-modulus shin plate, replaceable TPU toe slider, replaceable heel slider, and external side heel slider help protect against impacts and abrasion while promoting controlled sliding during an accident. Flexible microfiber accordion zones at the front, rear, and Achilles area support natural forward and backward movement without sacrificing coverage.
Fitment: The SMX Plus boots use an inner instep speed-lacing closure, lateral zipper, Alpinestars Lace-Lock System, and hook-and-loop zip-pull tab for a precise, secure fit and easier entry and removal. A micro-adjustable ratchet top closure helps secure the upper boot. The anatomical replaceable EVA footbed provides arch support and pedal feel, while the breathable ankle and leg lining, open-cell foam forefoot lining, and durable textured rubber sole improve comfort, shock absorption, grip, and riding control. These boots are designed to fit riders seeking protective footwear for sport motorcycles, track use, and performance-oriented street riding.
