Wow I have had my Sport Ultras for almost a year now and they don't look anything like that. I don't even untie mine when I removed them and I bowl at least 3 times a week. I would definetly contact Dynothane about that. That would be something I would expect for Dexter's not Dynothane. I went through 3 pairs Dexter's in a 4 year period.
