Since its launch in 2018, the QUILO from 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 limits of winter cycling shoe design. Our goal: to 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 category.

Performance and thermal protection

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

Comfort and control

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