I wear a 10 in most brands of shoe, occasionally wearing a 9.5D. I ordered these in red in a 9, and they are perfect. My toes do not bump the end, but they are nice and snug. Once the sheepskin smooshes down, they may feel a little loose, but I can always wear socks if needs be. I have bought a new pair of Ugg slippers every winter for years. I think I just switched to LLBean for the forseeable future! And they're cheaper too...
