I bought these shoes to wear mostly in the winter months here in Michigan to keep my feet warm and DRY, even tho there is no insulation in these shoes my feet stay warm in the winter, but I always seem to have "hot feet" These keep my feet dry all the time and they breath very well. I find myself wearing these all the time now even in the summer around the farm. I had walked threw 2 inch deep water with these and I still had dry feet. I was impressed with how they fit right out of the box, there was no break in time. This is my second pair of these same shoes and I love them.
