This is a comfortable sneaker, so it is worth a try, but I wouldn't wear it for serious running.  It doesn't have the right kind of support or structure for real running.
Also, I felt like 'I was sinking into the sneaker' at times.  I guess this is because it lacks arch support.  Besides that, I am overweight, so I need extra support because of my weight.
I ended up returning it, but I hate to say anything too bad about this shoe, because it was comfortable.  It is worth a try.
