Northwave Magma XC Core Winter MTB Shoes Black/Yellow Fluo Size 42

When winter trails turn icy and slushy, most cycling shoes force a compromise between warmth and pedalling efficiency. The Northwave Magma XC Core breaks that pattern with a Primaloft® 200g insulated upper and a carbon-reinforced sole that keeps power transfer crisp even at -10°C. Built around Northwave’s BioMap Aero Overlap construction, the shoe wraps the foot without pressure points, while the SLW3 dial and single strap lock the fit in seconds—even with thick winter gloves. The result is a dedicated cold-weather MTB shoe that feels less like a bulky boot and more like a precise, weatherproof extension of your pedal stroke.

Highlights

• Primaloft® 200g insulation for reliable warmth down to -10°C (14°F)
• Jaws Carbon Reinforced Sole with stiffness index 8.0 for efficient power transfer
• SLW3 dial + single strap closure for micro-adjustable, glove-friendly fit
• Arctic 4Layer footbed (EVA/Aluminium/EVA/Felt) reflects cold and retains heat
• 360° reflective inserts for visibility in low-light winter conditions
• Reinforced toe and integrated heel system for protection and stability
• 2-bolt SPD cleat compatibility for MTB and cyclocross pedals

In daily use

On frosty morning rides, the Magma XC Core’s weather-resistant upper keeps feet dry through puddle splashes and light snow, while the Primaloft® insulation traps body heat without overheating during hard efforts. The SLW3 dial lets you fine-tune tension on the fly, and the single strap adds security across the midfoot. The carbon-reinforced sole delivers a stiffness index of 8.0, balancing efficient power transfer with enough compliance for hike-a-bike sections. Reflective inserts keep you visible in low light, and the reinforced toe shrugs off rock strikes. The Arctic 4Layer footbed reflects cold back toward the ground, so your feet stay warmer longer. All this in a shoe that weighs just 310 g per side (size 42).
