I followed the reviewers and ordered down 1/2 size (I normally wear an 8.5 but ordered an 8.)  An 8.5 would have fit perfectly, but alas.  I needed a pair of muck boots for when I go out photographing birds - you never know what you'll be stepping in.  This fun color is easy to hose off.  I liked that they only came up ankle height as I kinda have fat calves and didn't want to worry about them not fitting but they were fairly comfortable.  I wouldn't want to wear these for a long time as they're not as supportive of an athletic shoe, but they provide waterproof footwear.
