Extended Product Information
FAQs
Are these waterproof?
No, the Slipstream is made of nylon to block wind and improve aerodynamics; they are not intended for heavy rain protection.
Can I use these with mountain bike cleats?
No, these are designed for road-style cycling shoes with smooth soles and standard 3-hole cleat patterns.
How do I choose the right size?
Sizes should correspond to your standard road cycling shoe size for a snug, aerodynamic fit.
Will these keep my feet warm in winter?
They offer moderate wind-blocking capabilities for cool weather, but are not insulated booties for deep winter riding.
Are they machine washable?
Hand washing is recommended to preserve the elasticity and integrity of the nylon material.
Troubleshooting
Cover bunching at the heel
Ensure the heel opening is properly seated at the base of the shoe's heel cup before pulling the front down.
Cleat interference
Verify that the material is pulled clear of the cleat engagement area to prevent clipping difficulties.
Pros and Cons
Pros
- Significantly reduces wind drag
- Protects expensive cycling shoes from road grime and dirt
- Durable construction lasts longer than standard cotton socks
- Provides a clean, professional aesthetic
- Secure fit provided by the 4-inch cuff
Cons
- Not compatible with mountain bike or casual shoes

Setup, Compatibility & Care
To install, place the Slipstream cover on your foot before putting on your cycling shoe. Once your shoe is secured and buckled, pull the cover down over the heel and the front of the shoe, ensuring the cleat cutout is aligned perfectly. These covers are compatible with most standard 3-hole road cleats. To maintain the life of the nylon fabric, hand wash in cool water with mild soap and hang to dry. Avoid using aggressive detergents or machine drying, as high heat may degrade the elasticity of the cuff.
