I received these a few weeks ago and have ridden with them several times. Their best feature is they are thicker and more substantial than most toe covers. I have ridden with these in temperatures from 50 all the way down to 30. Anything lower than that you will certainly need booties. If your toes get cold easily then you might want to go to booties earlier. Most toe covers I have used are much thinner and I have to put on booties much sooner. They have thick bottoms so if you wear mountain bike shoes they won't wear through easily. Great set of toe covers, highly recommended
