I've used these down to 32F. I have pretty cold feet, so yes my feet were still cold but not numb and frozen. For me, that's a game changer!
These shoe covers have so far kept my feet warm during chilly weather rides. Out riding at 35F and kept the feet warm.
I needed new shoecovers for my MTB shoes because I do a lot of gravel riding, and these fit the bill perfectly. My feet stay dry on 3-4 hour rides, which is exactly what I was looking for.
