I did a little research to find out which running shoes suit me best. After all the searching, I decided these are the ones that fit my specific needs and desires. They are really light, very breathable to keep your feet cool and very comfortable for long distances. I rode them a total of 24 miles the first 2 days. And they didn't disappoint me at all. And the flex of the shoe has really improved my normal run times. They will definitely get you ahead. I highly recommend it. So far no complaints at all.
