I can't give you a scientific answer for these. I bought two pair. For the price I think they are a pretty good shoe if you are not a long distance person. I'm about 190 and I think for my size I feel better in the higher priced Asic that I replaced. I doubt I'll buy next time but I would recommend by saying the price equaled pretty good value. I'm older now and I I walk as much now as I jog. They run pretty true to size and the colors are great.
