QUILO X4 BOOT Recommended temperature: up to -20 °C / -5 °F

Since its launch in 2018, the QUILO by Blivet Sports has become the ultimate choice for winter cyclists seeking comfort, warmth, and performance.

The 2025 version - QUILO X4 - marks a major evolution. Completely redesigned, it pushes the boundaries of winter cycling shoe design. Our goal: increase thermal protection without adding weight or compromising its unique style. The result: a more mature, more technical shoe, while remaining the lightest in its class.

Performance and Thermal Protection

• 3M™ Thinsulate™ 400g insulation - double the previous generation, offering increased warmth while maintaining the QUILO's legendary lightness.
• New Blivet Sports THEREX membrane (10K mm / 10K g/m²) - laminated to the inner fabric, offering exceptional waterproofing and optimal breathability during intense activities.

Comfort and Control

The Vibram® Wolftrax® sole ensures exceptional grip, increased stability, and uncompromising power transfer. The LISZT AIR TOEBOX offers generous 4E+ volume in the toe area, keeping your feet warm and protected from cold surfaces. The dual independent lacing system allows for a precise fit, while the calf strap (21 cm total height) effectively blocks snow.

• New THEREX membrane (10K / 10K) for a perfect balance between waterproofing and breathability
