Reflex WP Black Out Shoe Cover

Few things can ruin a ride as quickly as frozen toes, so when you're braving the cold and wet you'll want something like these Reflex shoe covers to keep your feet warm and dry. Windproof, water-repellent fabrics are joined with taped seams to seal out the elements, and come equipped with a fleece lining for extra warmth. 360-degree reflectivity helps you be seen during the shorter daylight hours of winter, while the durable fabric under the foot resists wear-and-tear.

  • Keep your feet happy with these weatherproof shoe covers
  • PU-coated fabric blocks wind, water, and cold
  • Taped seams go a long way toward keeping water out
  • Fleece lining helps your feet stay warm and cozy
  • High degree of stretch for a comfortable fit
  • Waterproof zipper for easy on and off
  • Sole accommodates 3-bolt road cycling cleats
  • Reflective details all-around to help you be seen

Hot due to Frustration

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: XXL

Based on other reviews noting they run small, I ordered the XXL as my shoes are a size 45. If I needed to fit on my road shoes, the Reflex covers would likely fit, but . . . since I intend to use these in the cold-freezing weather, I use mountain biking shoes for the additional traction. These covers require significant effort to pull over the rubberized tread and nearly impossible to pull over the heel. So while I was successful once, the second time I spent 5+ minutes trying to get one on but gave up as I was due to meet up with my fellow breakfast riders and did not want to be late. Instead, I had cold toes for the entire 2 hour ride.
These are really well constructed and would keep your feet warm. Just order a few sizes larger than what you think you need.


  • Familiarity: I returned this product before using it
  • Fit: Runs small
  • Size Bought: XL

These covers work great, especially for price point. Warm and dry. I also like the fact they aren't covered with logos.

I wear a size US 11 (45) shoe. XL's did not fit. XXL's fit fine. So size up!
