I purchased these with my only intent being to use them for Beachbody's Insanity workout program.  I must say, they are great... never have my feet hurt wearing these (the rest of my body has, but that is due to the workout!).

I did have to have the pair of shoes replaced after a week.  The stitching came out on one of the shoes.  I contacted ASICS and they told me I would have to pay shipping to them, and back, and it would take 3-4 weeks.  I contacted Amazon, and they overnighted me a new pair, and paid for the shipping back to them.  Amazon is a great company that takes care of their customers.

I highly recommended this shoes for any workout! Dig Deeper!
