What customers say
Winter cyclists overwhelmingly praise the 45NRTH Wølfgar Wool Felt Inner Boot for its exceptional thermal performance in extreme cold. Reviewers consider this liner a critical component that maintains the system's legendary warmth, keeping feet comfortable during long, subzero rides. The dense wool felt construction is noted for its premium quality, effectively extending the lifespan of the expensive outer boot.

Despite the premium price, satisfaction remains high among dedicated users who rely on this liner for the highest level of cold weather protection.
Know before you buy
No, these liners are specifically engineered for the 45NRTH Wølfgar winter cycling boots. They will not fit correctly in other models.
Having a spare pair allows you to rotate liners between rides. This ensures you always have a completely dry, fresh set ready to go, which is essential for maintaining warmth during multi-day trips or back-to-back winter rides.
The wool/polyester blend is chosen for its ability to wick moisture away from your skin while maintaining its insulating properties even when damp. This combination offers better temperature regulation and comfort than pure synthetic materials.
The hook-and-loop closure secures the liner inside the shell of the Wølfgar boot. This prevents the liner from shifting or lifting while you are pedaling, ensuring a consistent fit and preventing heel rub.
To preserve the integrity of the wool fibers, we recommend hand washing in cool water with a wool-safe detergent and air drying away from direct heat sources. Avoid machine drying, as it can cause the material to shrink or lose its shape.
