Everywhere I looked there were differing views on the fit of these boots.  Some said buy bigger, some said buy smaller.  I bought the black in a size 8 here on Amazon because they were half price and I usually wear an 8.5.  There is PLENTY of room for thick socks (they are thin, not particularly warm, so this is good).  I find them easy to pull on, though not as easy as a pair of Emu boots that I have.  They have a bit of a "Herman Munster" look to them due the Fit Flop sole, but I kind of like that look.  I don't know about the leg toning claims, but I do find them comfortable to wear all day.
