ALPINESTARS SMX+ Boots - Black/White/Yellow Fluorescent - US 12 / EU 47 2221019-125-47

Track days, street riding, and everything in between demand boots that won't compromise on protection or comfort. The ALPINESTARS SMX+ delivers a meticulously engineered package of impact resistance, breathability, and secure fit—all wrapped in a lightweight design that lets you focus on your line, not your feet. Whether you're chasing lap times or commuting in style, these boots combine race-proven protection with practical everyday wearability.

Built for riders who refuse to settle, the SMX+ features advanced microfiber construction paired with strategically positioned TPU reinforcement at high-impact zones. The Multi-Link Control system and wide heel counter provide ankle stability without bulk, while replaceable sliders on toe, heel, and side mean you're investing in longevity, not disposability. Micro-adjustable ratchet closure and speed lacing ensure a dialed-in fit every time you pull them on.
