I purchased these about a year ago from STEP. I've used them a few times in competitions and about 10 times in practice. The plates are still very stiff! There's some tartan color on the toe area. Also, the rebound material is slightly scraped from hitting the starting block, but it doesn't affect performance. I threw away the original box, so I'll use a Maxfly 2 box as a substitute. I'm open to some price negotiation, so please comment with your desired price.
