I work in a busy Garden Center and spend much time outside in the cold, rain and mud. These have saved my life! Love them. I ordered a 1/2 size up so they are comfortable with my heavier socks. The memory foam is soft and "cushy". They are water proof and keep my feet dry and WARM! The high rubber bottom  helps me to keep my feet directly out of the mud. Have tried many different boots - these are the best!
