RSR Winter Speed Booties

Assos RSR Winter Speed Booties

The Assos RSR Winter Speed Booties are lightweight winter overshoes with clear racing DNA and a precise, aerodynamic silhouette. Assos combines the speed-oriented shape of the summer model with genuine winter protection – windproof, waterproof and pleasantly warm. Thanks to the zipless construction, volume is reduced so the booties can be worn easily under winter tights without chafing. An elastic, body-contoured shaft wraps around the calf like a second skin in zeroPressure fashion.

• Aerodynamic, low-volume fit without zip
• Airblock.888 membrane at ankle for wind and weather protection
• NEOS Medium 3L Softshell at forefoot for insulation and breathability
• SportGrip sole area for grip when walking
• Designed for layering under tights for friction-free wear
• ZeroPressure second-skin fit at shaft for comfortable finish

Technical Details and Features

At the ankle, Airblock.888 is used – a medium-weight, proprietary membrane that insulates and reliably shields against wind and water, keeping your personal microclimate stable. Over the forefoot, Assos uses NEOS Medium 3L Softshell, a breathable, insulating laminate that supports thermoregulation while maintaining the slim, aerodynamic shape. The zipless construction with body-mapped panels reduces potential weak points and ensures a flush, zeroPressure finish. Under the foot, a SportGrip insert increases durability and provides traction when you dismount or take a section on foot. According to the manufacturer, the material components consist of Ankle: 41% Polyester / 38% Polyamide / 21% Elastane and Front part: 47% Polyester / 35% Polyamide / 18% Elastane.

Applications and Benefits

These overshoes show their strengths on fast road bike rides in Swiss winter as well as on daily training kilometres or commutes. The combination of windproofing, waterproofing and controlled breathability keeps feet warm longer without heat build-up. The low volume makes them ideal for riders who want to pull their winter tights over the booties to achieve a clean, smooth aero edge on the leg. The zeroPressure finish sits comfortably, minimising pressure points and improving compatibility with different leg lengths. Those who value a clean look and race-oriented performance get a functional upgrade for cold, windy and wet conditions.

Optional: Fit, Size Selection and Care

Pull the booties carefully over the shoe before starting and align them without tension so the SportGrip zone sits correctly. Thanks to the elastic construction, the shaft fits snugly without constricting; combine it with smooth winter tights for maximum aerodynamics. Remove dirt after rides with a damp cloth and let the overshoes air dry to maintain membrane performance long-term. Avoid sharp edges when walking and use the booties primarily on roads and paved surfaces to extend their lifespan.
