I received these boots for my birthday from my son. The last rubber boots I wore were from my childhood and were very loose. These boots feel great and needed no break in. I put them on and wear them all day and forget that I'm even wearing rubber boots. Plus they look great. They can get a little warm but no more than a normal hunting boot. I wear a size 9 and thats what these are and they are true to size. I would buy this brand again over another , because how could it get any better.
