Developed through a blend of Italian design passion and relentless technical innovation, the Stylmartin Stealth Evo Air racing boots are engineered for serious track performance. Purpose-built for high-speed riding, they deliver advanced protection, precise control and maximum ventilation where it matters most.
The vented microfibre upper and breathable air mesh lining work together to keep airflow moving during intense track sessions, helping regulate temperature and reduce fatigue. A sophisticated ankle floating system supports natural movement while limiting torsion, improving stability and rider confidence at lean.
Protection is comprehensive and race-focused, with PU ankle reinforcements, a moulded shin plate, PU heel support, and shock-absorbing internal padding. A replaceable titanium toe slider adds professional-level track functionality, while the reinforced gear shift protector ensures durability in high-contact areas.
Secure closure comes via a zip system combined with ratchet straps and a micrometer buckle, allowing fine adjustment and a locked-in fit. Finished with a hard-wearing anti-slip rubber outsole, the Stealth Evo Air is designed to perform lap after lap.
