Blivet QUILO FLT X4 (Flat Pedal) Winter Cycling Boot (NEW) | 🍁
Blivet QUILO FLT X4 (Flat Pedal) Winter Cycling Boot
After introducing the original FLT in Dec. 2022, we kept in touch with our happy ambassadors and consumers collecting multiple comments and suggestions. This was so exciting and constructive, we just had to go further in the FLT concept and blend a new version of this exceptional boot to rise the bar even higher. And this time in a stunning ''stealth'' black... yes sir!
FLT WHY: Pedaling dynamics in the snow is key to good traction and power delivery to the pedals. When it comes to flat pedals we know that maximum contact between boot and pedal are key, we don't want the wrong position, we don't want the pins to get stuck between large threads. From now on, there is no need to ride in your summer riding shoes to get that perfect contact and delivery of power.

FBC Boot Purchasing Guide
FBC Boot Purchasing Guide
Finding the right pair of boots is key for comfort, performance, and durability. At FBC, we carry boots designed for outdoor adventure, cold weather, and everyday wear. Use this guide to choose the best option for your needs.
1. Determine Your Use Case
Different boots are built for different conditions. Start with where and how you’ll be using them:
- Casual Winter Wear / Easy Riding – Choose warm, waterproof boots that emphasize comfort and style.
Active Winter Fat Biking – Look for lightweight, insulated boots that work with wide platforms or clipless pedals, and have waterproof protection.
Backcountry / Expedition – Go for highly insulated, extreme-weather boots that prioritize warmth and waterproofing.
Commuting / Everyday – A versatile option with moderate insulation and all-day comfort.
2. Fit & Sizing
Try with your intended socks. Thicker socks may require sizing up.
Toe room is crucial. Cold-weather boots should allow a little extra space for circulation.

Light (0–200g): For cool, active use.
Medium (400–600g): Versatile for most winter days.
Heavy (800g+): Extreme cold or low-activity conditions.
Waterproofing
Look for Gore-Tex, proprietary membranes, or fully seam-sealed boots.
Pedal Compatibility
Flat pedal boots: Grippy rubber soles.
Clipless-compatible boots: SPD or 2-bolt cleat mount options.
Height & Support
Low-cut: Lighter, more flexible.
Mid-cut: Balance of support and mobility.
High-cut: Maximum warmth and ankle protection.
Sole Flexibility
Stiffer soles: Better for cycling efficiency.
Flexible soles: More comfort for walking.
4. Temperature Ratings (Approximate)
Mild winter (2°C to -10°C / 32°F to 14°F) – Lightweight insulated boots.
Cold winter (-10°C to -20°C / 14°F to -4°F) – Mid-insulated boots.
Extreme cold (-20°C and below / -4°F and colder) – Expedition-level boots with heavy insulation.

Always dry boots fully after use to maintain insulation and waterproofing.
If in doubt, size slightly up and adjust fit with socks or insoles.
