Sidi Aeron XC Clipless Mountain Shoes

Aeron redefines XC performance through advanced construction, precision fit, and race-ready efficiency. Built for clipless control on technical trails and fast courses, the ripstop upper with TPU bumpers protects against abrasion and impacts without adding weight. Dual NUUN 001C dials pair with an adjustable instep and UNUM tongue to deliver micro-precise tension and a pressure-free wrap, while the external Firmor reinforcement and tool-free heel adjuster lock in stability for confident pedaling and quick dismounts.

Underfoot, the X2FC full carbon sole with stiffness index 11 channels maximum power transfer for explosive acceleration, while generous rubber coverage and integrated toe lugs provide secure traction for hike-a-bike sections and slick terrain. The result is a responsive, supportive XC MTB shoe that balances lightweight speed with durable protection and a customizable, dialed fit for training, racing, and all-day trail missions.
