I purchased these shoes as a recommendation from a friend.  I normally used my Nike's for working out, but due to their bulkiness and weight, my feet tended to burn or cramp - generally just uncomfortable.  Please note the Nike's I have are not workout shoes.  I love these shoes because they are light and very comfortable. I not longer have the sensation of "tired" feet during or after my workout.  I typically purchase mens shoes for the colors available - not too thrilled with some of the colors offered by "womens" shoes.  I was very happy that these womens workout shoes weren't too girly in regards to the colors (lime green, black, and white). Overall: Very comfortable. Great fit, great feel, great color offered.
