Those are good for walking or running. Why only two stars then? Well, in the product photos you can see that the sole has an extra 'layer' glued to it (orange, black of whatever the color might be). That layer started coming off.
I work out in a gym that has that typical green carpet that imitates turf. I do lots of running and changing direction and the shoes dig into the carpet. All those rapid changes of direction made the edges of that layer come unglued and start breaking off small pieces. I have two pairs and they both do the same. I used super glue to repair them but it didn't hold. All in all, I'm quite unhappy with the shoes.
