Stiff, walkable MTB performance with wide-fit support in the Aertis Mega Mountain Clipless Shoe
What Our Gearhead® Experts Are Saying:
"I recommend this shoe for riders who want XC efficiency but need more room in the forefoot. The SR17 sole feels efficient on climbs, and the dual-dial Tecno-3 system keeps the fit precise. It’s a solid option for technical trails and gravel rides where durability and comfort matter."
The Aertis Mega Mountain Clipless Shoe is built for riders who demand efficient power transfer without sacrificing off-bike comfort or fit. Designed by Sidi for cross-country and gravel riding, it combines a wide-last construction with proven closure technology to support long, demanding days on mixed terrain. The premium suede upper offers durability and structure while maintaining a supple feel that reduces hot spots over extended rides.
Sidi’s Tecno-3 system uses dual micro-adjustment dials to fine-tune tension across the foot, working in tandem with the Firmore closure to create a secure, evenly wrapped fit. This design enhances stability during hard efforts and technical sections, while still allowing quick adjustments on the fly. The MTB SR17 sole is engineered to be stiff enough for efficient pedaling, yet flexible enough to remain comfortable when walking or navigating hike-a-bike terrain. Replaceable toe inserts further extend durability for riders who frequently encounter rocky trails.
Whether lining up for cross-country laps, heading out on long gravel routes, or tackling mixed-terrain adventures, the Aertis Mega Mountain Clipless Shoe delivers dependable performance, wide-fit comfort, and long-lasting construction for riders who expect more from their footwear.
