Slicker Pull-On Shoe Cover

Barring any serious thunderstorm type weather, bike races go on no matter what clouds are in the sky. Castelli's Slicker Shoe Cover keeps our feet dry and shoes aerodynamic when the clouds bring rain during our ride or race time. The pull-on design and stretch fabric eliminate potential weak points where water could enter and enhance the close fit around your shoe and ankle to keep rain out of your socks. At only 80grams, we barely notice the added weight on our feet, while savoring the dry feel on a rainy day.

  • A seamless shoe cover to protect from the rain
  • Flexible fabric pulls on over shoes and socks for an aero fit
  • Waterproof and seam-sealed upper for optimal protection
  • Reflective details enhance visibility while on the road

    What do you think about this product?



    What would the approximate weather temp rating be for these? Would they help keep toes warm in the 40º-50ºF range?

    Super tight- size up!

    I've used it once or twice and have initial impressions

    Great in terms of warmth and water resistance for 45-65F type temperature and showers. Haven't tried in a downpour yet. Very difficult to get on though, I'm a 42 and got M, which I'm sure it's too small and I'm likely to rip the material soon enough... It's like a really tight balloon. Overall, good replacement over my neoprene ones and those with a zipper that let the rain in the seam.

    Total Garbage

    I've used it once or twice and have initial impressions
    Runs small

    For the second day in an row I find myself reviewing shit product from Castelli. I’ve tried multiple ways of getting the cover on & none work. I’m on the small side of the size range suggested & STILL can’t get the covers on. Shame on Castelli for manufacturing poorly designed & produced products & shame on Competitive Cyclist for peddling this crap.

    Thank you Castelli!!

    True to size

    Before finding these shoe covers, I was on a quest to find a replacement for Castelli's earlier zippered version of the product. That is, a shoe cover that was aero, light, water-resistant, and super cool! And those covers were awesome until the zipper broke. My search for a replacement was fruitless, with a couple of dead-end products that just didn't make the grade. And then, right here on Competitive Cyclist, I saw Castelli's Slicker pull-on shoe cover. Looks promising. So I decided to take a chance on them. The end result: I am super happy with this product! There is a caveat (more on that in a moment). But this is the one. Nice tight fit, aero, and water rolls right off. Everything I was seeking for the early Fall riding, as well as into Winter (other than the coldest weather). So big thumbs up! Ok, the caveat. If you buy these covers they do NOT come with info on how to put them on. Based on experience with another brand, here's how: First, put on your socks, then the shoe cover. After that put on your shoes and work the lower part of the cover down and over the shoes. To remove, just reverse the steps. If you do try to pull the covers over your shoes, you'll be disappointed. You would need to be massively strong and will likely wreck the product in doing so.

    A novel idea for putting them on and taking them off...

    The new line of Assos booties use the same on/off technique. the factory site has a demo.
