I bought a pair of boots at the beginning of winter and after wearing them for a month or so my feet would freeze and get wet. I started searching for a pair of boots that would be both warm and waterproof and I came across the crocs. After reading the reviews I decided to try a pair and I am glad I did. I bought the yellow pair as they were half the price of the black ones...for $40 less, I didn't care what color they were! I am out in the elements all the time for work and these boots have not let me down yet. I did buy a size larger and at first I was unsure if this was the right decision, but I like to wear heavy socks, so the extra room allowed for this. If I had gone with my true size I think they would have been too tight with fuzzy socks. I have gotten numerous compliments on my yellow boots and I wear them proudly! Next year, I plan on buying these boots for the whole family.
