**these run a half-size small--I'm a 7.5 and the size 7 shoes fit perfectly**

I have read two things that happen when you wear these often: 1) they become more flexible over time, and 2) the top mesh gets torn very easily. I will update my review if anything negative happens. So far, after purchasing them today and walking around a bit, they're great.

FIT: No less time-consuming to put on than lace-up sneakers--slip your foot in with the help of the cord, and strap up. Although more fitted than tennis shoes, these aren't nearly as flexible as "true" barefoot shoes--I have no toe mobility in these, and I can't bend my feet either. The pads on the bottom are firm (i.e. not really soft/cushioned), but contour my feet nicely. Overall, the fit is great and I can't imagine these causing blistering or pain.

CONSTRUCTION: Looks rather cheap--even in some stock photos online, you can see sloppy glue-work on the toes. That, and the fact that they tear easily, is why I'd give them 4/5 instead of 5/5. The velcro closure system is vaguely reminiscent of toddler's shoes.

APPEARANCE: Who knows why Amazon called these 'fashion' sneakers--they look ridiculous unless you're near water. My whole family had a good laugh when I modeled these babies. I don't intend to wear these out in the public, unless I'm running or doing some light hiking.

If you live a diehard 'natural foot' lifestyle (i.e. ultra-flexible, thin), definitely look elsewhere--otherwise, they're great. Overall:
PROS: great traction on most surfaces, as compared to regular sneakers; comfortable; fitted.
CONS: cheap construction, lots of complaints online of ripping; inflexibility; unaesthetic appearance.
