i'm wearing my second pair of clogs, as they are sized very large and i had to return and size down.  they are sooo comfortable and lightweight, that i could almost wear them as slippers.  they are flexible and appear to be able to withstand ice.  some synthetic soles become rigid on ice.  i gave it 4 stars, as i don't think that they are sized correctly and the upper material is very shiny.  i feel like i'm wearing satin.  bet that they would look great in suede.
