The idea of wearing rubber boots in the winter is nothing new, but they’re becoming more and more common.
Now, there are more than a million pairs of shoes sold in the U.S. every year, and there’s plenty of research that suggests that wearing rubber can increase the risk of cold weather-related injuries.
The American Academy of Orthopaedic Surgeons says that the rubber boots could also increase your risk of frostbite, which can happen if you fall into a deep crevasse or fall down a steep slope.
The idea that rubber boots should be avoided in the cold has been around for a while.
But now, researchers are starting to show that wearing them in the heat can actually make you a bit warmer.
According to a study published in the Journal of Applied Physiology, wearing rubber shoes in the summer actually made you slightly warmer than people who were not wearing rubber.
This may sound crazy, but this is the sort of thing that can happen when you wear rubber shoes to get warm.
Rubber boots may help prevent the cold from hitting you, but it’s important to realize that the cold is still there, and wearing rubber will do nothing to make you feel any warmer.
