DescriptionThe whole story

Not every ride is a track day. The Sidi ST Air motorcycle boots in black are built for the rider who wants one boot that does it all — the daily commute, the weekend blast, the long summer tour — without ever cooking your feet along the way. Drawing on more than 60 years of Sidi bootmaking, the ST Air is the brand's ventilation specialist: a genuinely breathable, multi-purpose sport/street boot that still carries the ankle and heel protection every road boot should have.

Key Features

  • Fully vented, highly breathable microfibre upper channels air across the foot to keep you cool on hot commutes and long summer rides
  • External protectors on the toe, heel, side and calf shield the most vulnerable areas from impact and abrasion
  • Fast, secure zip closure system with supporting strap gets you in and out in seconds and stays put on the move
  • Shock-absorbing heel cup and full-length ankle support braces add stability without fatiguing the leg
  • Durable high-grade microfibre construction engineered for years of everyday use
  • Replaceable buckle and strap, shin plate and slider let you refresh wear points and extend the boot's service life

Ventilation Built for Everyday Riding

The ST Air earns its name. A highly breathable textile-and-microfibre upper works with Sidi's Air Ventilation System to move air through the boot as you ride, drawing heat away from the foot on stop-start commutes and multi-hour summer tours alike. Where heavier sport boots can leave your feet sweltering in traffic, the ST Air stays comfortable — making it a natural choice for warm-weather riders who spend real time in the saddle.

Protection Where It Counts

A ventilated boot is only worth having if it still protects. The ST Air carries external protectors across the toe, heel, side and calf, guarding the areas most exposed in a slide. A shock-absorbing heel cup cushions and stabilises the heel, while ankle support braces run the length of the boot to resist twisting and hold the ankle securely. The replaceable slider and shin plate mean the boot keeps doing its job after contact with the tarmac rather than heading for the bin.

Comfort, Control and Everyday Versatility

Sidi designed the ST Air from the ground up as a true multi-purpose boot. Side braces support the entire structure so the boot stays planted and your leg stays fresh over long distances, while a sleek inner keeps you close to the bike for precise feel at the controls — control being the first step towards safety. A zip closure with elastic panel wraps the foot snugly, and the road-riding sole delivers long-lasting comfort and grip whether you're filtering through town or covering ground on the open road.

Fit and Sizing

The Sidi ST Air is offered in a regular fit across a broad European size run, from EU 37 to 50. If you ride in thicker socks or sit between sizes, we recommend sizing up. As with all Sidi footwear, consult the Sidi size chart before ordering to confirm the best fit.
