They're definitely expensive for a rubber sandal. They have a slick marketing campaign that claims they'll tone your muscles as you walk, and a few wearers say they even reduce lower back pain. While some benefits apparently have been proven by laboratory tests, the prudent consumer will take these claims with a healthy dose of skepticism--"Your mileage may vary." They may not be styled to everyone's liking. Most women can probably find a style and color to please them, but men are limited to just one style in two colors. But other considerations aside, Fitflops are worth buying for one simple reason--they are unbelievably comfortable. You can wear them for hours and not even be aware that you have them on.

If you read the other reviews, you'll find a lot of conflicting information about sizing, fit, quality, durability, etc. Some reviewers say to size up; others say to size down. Some say they notice a muscle toning effect; others say they don't. Some say Fitflops are well made and durable; others say they're junk and started falling apart immediately. I offer the following personal observations: 1) Fitflops run slightly large, but not exceptionally so. If you're a half-size, I recommend sizing down. My wife normally wears a 6.5, but her size 6 Walkstar fits her perfectly. 2) They are very well made, although I do wonder about the long-term durability of the very thin toe thong. The straps, sole and footbed all are made of high-quality materials, and are very well put together. 3) Based on a his-and-hers sample of two pairs, they have no manufacturing defects. All in all, they seem to be of extremely high quality.

If you're looking for a distinctive, lightweight, comfortable and (possibly) beneficial sandal, and don't mind paying a fairly steep price, I highly recommend that you give a pair of Fitflops a try.
