QUILO FLT 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 looking for comfort, warmth and performance.

The FLT was designed specifically for fatbike riders who demand the best in pedaling dynamics on snow. Its design ensures optimal contact between the shoe and the pedal, offering superior traction and power transfer, crucial for winter cycling.

The 2025 version – QUILO FLT 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 retaining 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® Fort William® sole ensures exceptional grip on flat pedals, increased stability and uncompromising 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 for a precise fit, while the calf strap (total height of 21 cm) effectively blocks snow.
