These are my first Fly Flot shoes, and they are extremely comfortable!
They are very soft and comfortable, appear to be well made, and are cute!
The sizes may run slightly short with these. I wear either 9.5 or 10, and these "just" fit in length, despite being marked as for 9.5-10. I had read a review elsewhere that commented these run short. That reviewer suggested buying a size larger than normal. In my case, I think the next size up would be too long, but it does seem to run a bit short.

I find that when i wear these shoes my knees do not hurt. AMAZING!
