I have loved the ecotread flips for years, but I loved the color of these , so I decided to try them (free returns, why not?). I bought another pair of the ecotreads (on sale!) at the same time--and compared to those and my current pair, these ones flipped a lot more when I walked. The arch support felt pretty much the same, but the sound bugged me and since they cost more than the others, I returned them.
