I had big hopes this shoe would work out. I had a pair of gorun2's but they did not work. I had hoped this one would work. The shoe does not breath well. I had the same problem with the gorun2 but I though this shoe has to be better. I was wrong. I though I could at least walk in the shoe if nothing else. Well, It is really not that great for walking either. It does not feel bad. It feels sort of ok. The biggest issues are breathable; poor build quality and very poor wear. I get tired faster also. One day I went out for a run and in less than .5 miles it was just not fun, so I walked home and changed shoes. I ran the entire course and set a PR in the shoes I changed to. The shoe I changed into were a very high-end shoe similar to a racing flat but the difference was unreal. I had wanted to try the bionic but have seen complaints on its breathability also.
 I do think the shoe is better than some ratings as the midfoot support is strong. It is too much for me and I have high arches. I was sure I could make it work but it looks like I was wrong. This shoe is cheaper and looks more durable than the gorun2 but I think they are still behind most major shoes companies out there.
 I will update If I have better luck. I have put a lot in tring to make this shoe work.
