I only wear Nike shoes, for walking. I am an avid speed walker. I purchase a pair every 3 months. I put 500 miles on my shoes as I walk 10 miles a day. I'm so disappointed in these shoes. They are so narrow in the toe box. I cannot wear them. Sure, they look great, but they are the most uncomfortable Nikes ever! I have never had corns, or pain in my feet ever from speed walking. I have one corn on my right baby toe. Granted I have wide feet, but Nike tennis shoes always run wide. Not, this style. Do yourself a favor, if you have even a tendency toward a wide toe box do not purchase these shoes, no matter how beautiful you think they may look. If you do, you will end up with extremely sore feet and potentially corns, bunions and other problems. Nike has many other awesome styles to choose from. This style comes in a variety of beautiful colors and are sold at many different department as well as Nike and other shoe stores. Don't be tempted by the beauty of them. They will BITE YOU!
