I bought these shoes 4 months ago and the little black rubber parts of the sole on one shoe are coming unglued or already have. This shoe is only worn at the gym maybe 6 hours a week. Light cardio. This should not have happened, and now it looks like I'm out 75.00....The shoes look good and felt pretty good for 75.00 dollar shoes but the bottoms coming unglued is unacceptable after such little time and use.
