I purchased these shoes for my wife. She is an absolute workout warrior. If it doesn't hurt, you are not working out hard enough. I worry about her hurting herself all the time. She had another pair of this brand of shoe which lasted for years. I finally realized she had worn the tread off of them and bought her a new pair. ON AMAZON WE PAID WAY LESS THAN HALF THE PRICE WE PAID FOR THE OTHER PAIR AT THE RUNNING STORE! She is not one to make a big deal about her shoes or any other workout gear but she has commented, out of the blue, several times in the last 2 weeks that she has had these shoes how they feel fantastic, form around her feet perfectly, provide great traction, and have made her knees and ankles much more comfortable. This is from extreme cardio workouts with LOTS of jumping, lunges, on the ground and back up, etc. They are clearly the best shoes she has ever had. She also thinks they look terrific and wants me to buy her another pair for casual wear.
We highly recommend these shoes, buy them from Amazon and save some money.
