I have been using the Pro for several years. I had them when they first came out, and like some others on here, they didn't last more than a season. Since the first time I used them, they have been changed a lot. The toe and heel have been redesigned and beefed up. I noticed the box for this year says that they are 20% stronger - using a heavier compound. I love these for the simpleness of the design - they really work.
