Last summer, I discovered that I just wasn't wearing any other shoe than my FitFlops, because nothing else felt so comfortable--and the shaping up angle was a big plus. Darn those dressy events when I had to put on heels! When the winter Fit Flops came out I was first in line to get them. This black Gogh Clog is my favorite. I wear it with everything but the dressiest outfits. And now you can get it in gray and charcoal too. Plus try out the Willow version, which is shearling inside and so warm you'll love it. I'm really considering FitFlop boots. They are expensive, but somehow I'll find a way. I do have MBTs, but honestly, they are almost painful to wear, and FitFlops do the work in a much gentler way.
No, you can't skip the gym. There is the upper body to consider. But, wow, these shoes have practically changed my life. I want to give all my other shoes away--and if you know how many shoes I have, that's a drastic statement.
I didn't have to size up, but I have a very small foot (6), so they fit true to size.
