Have you heard of FitFlops? The dual-use fashion/fitness shoe?  (Seriously?)  Well, I'm here to say that the new winter line of FitFlops — the Gogh and the Billow (pictured) — are FABU!  It's not necessarily gonna make you feel the burn or start sweating away the calories.  Suffice it to say you can leave your sweatbands at home (or in the 80s, whichever you prefer!).  But there is definitely something going on there — it's the way they fit, they way they feel.  It's working something.  Fitness aside, though, they're super comfy, and the warm fur liner on the Billows are better than a snuggle by the fireplace.  OK, maybe not that good, but you get the picture.  FitFlop's winter line is available starting Thursday, Nov. 20.  Learn more at thefitflop.com, or find retailers here.
