Built for demanding XC riding and trusted by elite racers, the Sidi Hiemx is engineered to deliver warmth, protection and efficient power transfer in cold, wet conditions.
The upper combines textile and TPU with a weatherproof, breathable Gore-Tex® ePE membrane, reinforced by a soft, temperature-regulating Gore-Tex® fleece lining. This dual-layer construction keeps feet dry while maintaining thermal balance on winter trail rides. A durable Ripstop outer resists scratches and helps seal out water.
Underfoot, the X2NC sole blends nylon and carbon fibre (stiffness index 7) to channel power efficiently to the pedals while retaining enough flex for walking technical sections. Replaceable, high-grip inserts ensure traction both on and off the bike.
Fit and stability are refined through Sidi’s Firmor lateral support system, an anatomic heel counter and an impact-tested high-density dial closure with Dyneema® cable for secure, precise adjustment that holds firm all ride long. A reinforced toe guards against trail debris, while a reflective heel tab enhances visibility when rides stretch into dusk.
A rugged, high-performance MTB shoe designed for powerful cold-weather riding.
