They are intended for cool conditions in Fall or Spring. In that regard they work as advertised to give a little warmth. For Winter rides, you need the full shoe covers.
Can't say that my feet are warm, but this pair has helped as anticipated in the 40-50 degree weather. Carbon Fiber shoes are cold anyway, but I feel like they do add a protective layer to the front of the shoe from debris, etc.. A great deal on sale, but would not buy at full price.
I love these covers, they keep my toes toasty on long cold fall rides.
Good if you need a little insulation on 40-ish days. Below 40, they aren't much help in comparison to a full bootie.
I have use these down to 40F, and they seem fine. Under 40, I'm not so sure.
Neat little toe covers that keep your toes warm and protect your shoes when you can't be bothered putting on full shoe covers. I've enjoyed wearing these with mountain biking and road shoes.
I slip them over my Bontraged bike shoes. They are extremely easy to get on and off and kept my toes from getting cold.
These toe covers go on and come off easily. They fit snug on the shoe and provide a good barrier for wind protection.
I consider toe warmers to be to the lower extremities what a wind vest is your core. Easy to pockettake on and off and can replace full booties in 7.5 out of 10 situations. This is nice mid weight pair, which slots nicely between my thinner Pearls and my heavyweight neoprene models.
I've been using these toe covers for a while now and they are a great solution for those cool days where you need to shut out the flow of cold air coming into the vents of your cycling shoes. Combine these with some nice warm wool socks and you can keep your toes from freezing when the temp drops down into the mid-40s. Anything below that and you will likely need a full boot cover. I actually keep these on my shoes and wrap an additional cheap bootie around my feet to give me complete warmth. They are purely a wind blocker so they are very thin and can fit easily under a cheap pair of neoprene booties.
