Does it all and looks good at the same time.

Upon initial inspection, it’s clear that the Nano Shoe Covers are first and foremost intended to smooth the airflow over your bumpy, ratchety shoes. But once you start wearing them, you’ll realize that they serve so many more purposes. Made from silicone-coated Lycra, they keep you aero and actually protect your feet from the wind. The material also forms an effective barrier to the rain and cold so that you can wear these with confidence for your weekly time trial series and drizzly, gloomy October afternoons alike. In fact, if you have a warm enough sock, you can wear these babies in everything but the coldest conditions.

Good deal!

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: l

I have a pair of shoe covers but ordered these because of the stretchy covers. I love them. Gave my other set away to a cyclist friend. My feet stay warm, and they shed water very well. I really like the product.

poor made, don't buy

Sizing is way off!

  • Fit: Runs small
  • Size Bought: large

Smooth surface, seems water resistant, but ridiculously small if you expect to use them more than a couple of times! I wear a 42.5 Sidi shoe. The large, which is already a size over the sizing chart recommendation, was almost impossible to stretch over the cleat and the seams were extremely stressed. Returning for an XL - two sizes above the chart recommendation!

Ok But Returned Mine

    Quality appears just average here and design is a bit behind many other brands. Material is nice, waterproof and very aero but typical Castelli, it's sized too small making it highly likely that these will tear when trying to get over your shoe. Most brands today have a Velcro type strap underneath so it can fit over your clear easier. These are all one piece and it is a chore to get them over the cleat, the stitching on the piece between front and back cleats was stressing. Gore just came out with a light weight road in neon yellow with a seemingly much better design. I plan to buy those as many shoe covers are black, I do believe on cloudy, overcast / rainy days the yellow does help.

    Poor Quality

    • Fit: True to size

    These shoe covers are poorly made. The rubber/latex cover that gives them their water resistance started peeling off after 4 rides at the front of the shoe (along the seam) and also by the zipper. I threw them away after six rides.
