Ordering my normal size, the shoes fit tightly but comfortably with no socks, however that's what I wanted from muck shoes. I got the little goats on a blue background style, and I just love them! I use them when doing gardening so I can just leave them outside to either dry up where the mud just cracks off, or the rain cleans them off. No socks or muddy, messy or wet insoles to deal with.
