These are a great shoe. I have extremely flat feet and have been through numerous running shoes that just leave me in pain. I was running in Merrell barefoot shoes for about a year, but anything over 10k just left my feet in pain and I knew I needed more cushion. I tried on the other asics shoes for flat feet (like the evolution) and they just did not feel right on the run and left my foot at a weird angle. The Nimbus was able to overcome the pain i felt with flat feet. The most I ran in them was about 11 miles now and I have a 13.1 in a few weeks in which the only the "pain" I felt was tiredness. This is a major accomplishment because 1) I'm a bigger guy and 2) MY FEET ARE REALLLLLY FLAT.

I highly recommend these shoes. I put on about 20 miles a week now and have done a few races with them!
