ROCKBROS Cycling Shoe Covers Thermal Shoes Toe Cover Windproof Half Shoecover Water-Resistant for Mountain Road Cycling Shoes Black

Do the job! Great for SPDs

I've been commuting with these all winter in Chicago. I like them, but with a couple of caveats.1) The velcro strap on the bottom was too short and didn't actually help at all. I cut it off. Maybe my shoes are wider than RockBros expects. Either way, they stay on just fine, so I cut off the velcro strap that was always just flapping on the bottom of my shoe. The elastic does just fine on its own.2) For reference, these keep my toes warm and dry between 0-20°F. Chicago can be a little bit wet and a little bit windy. These do great. BUT, you will need to pair them with something like some mid-weight merino socks. These are not going to keep your feet warm by themselves. But they're a good ingredient.

These are great. I wear a women's size 9 and ordered the L/XL. They are just slightly loose, but I think the S would probably be too snug (just a guess). I wear Gyro SPD mountain bike shoes on my daily commute and these go on and off easily (even when the shoes are already on my feet.) There is a nice wide cut-out on the bottom, so there is no fabric interference when clipping in. I can clip in and out and walk around the same way I would without covers. I ride 5.5 miles to work in the roughly 35 degree morning air of Denver and these do a great job of blocking the wind. I will say my toes are slightly chilly by the end of the ride, but not frozen the way they were sans covers. They are I was between these and the Peal Izumi covers, and I'm glad I chose these because they feel thicker and they have a much wider cut-out, plus they were less-expensive!

Allows for your toes to be dry and warm in colder weather

With the recent cold snaps across the USA I found myself needing to keep my shoes warmer on my bike rides. I ride approximately 60+ miles a week and will ride in even the coldest weather excluding rain. I am 5'10 and wear a size 11 shoe. When I received these I of course tried them on and struggled getting them to go on my shoe as they are very tight. More concerning was the velcro used to attach. It simply will not reach the other side. If the entire product was a velcro strap it may be passable but they decided to save some money I'm sure and give you an inch of velcro instead of making the product much more useable with 3 inches of velcro. I found this oversight ridiculous. More concerning was how tight the product is around a size 11 shoe. I was in Florida this past weekend and planned to ride 100+ miles. The temperature was approximately 32 degrees with 14 mph winds that gusted to 20+mph. point being is that I could have used them. I initially put them on and rode for 30+ miles or so before my feet started to get very sore where the shoe covers were. I eventually removed them and after 10+ miles or so the pain diminished significantly. These may be good for small shoes and much more narrow but I would not imagine for anyone that wears a size 6-7 and above. Last but not least the velcro should not even be advertised.
