I purchased these new in January and have only worn them 7 times. There is no wear on the studs, and they are still in great condition and can be used without any problems. The black marks are from artificial turf and are not scratches or frays. I bought these for a coaching course and used them once for an hour on a dirt ground for a test run, and six times for two hours each on an artificial turf ground during the course. I will be fine with training shoes from now on, so I am selling these before they get worn out. This was my first time using cleats that tighten with rubber, but the fit was great, like wearing sneakers (do you understand?). The upper is made of a vinyl-like material, which is durable and resistant to snow and rain, which was also good.
