I started buying Fitflops a few years ago when I got suede Superboots, based solely on style.  When I discovered how greatly they relieved my foot and knee pain, I eventually switched over and wear Fitflops almost exclusively.  So getting the slipper was the obvious conclusion.

These are of substantial build, and not poofy or floppy like the average slipper.  They have a firm feel, not what the foot first expects from a slipper. The shearling lining is on the inside uppers but not on the footbed, and is cozy and comforting to the foot.  Because of the hard soles, it makes them practical for trips out to the yard, and these could actually be worn as shoes.

I have read various reviews relating to how to buy the right size, but I have found all their clogs, boots, and these slippers to run true to size. Because I like them so much, I recommend Fitflops to all my friends.
