Was in the car most of today and had on SXM PGA Tour Network on almost the whole time. Brian Katrek played an interview he did recently with the Chief Designer for Nike who worked with TW on the Free 13. It was very interesting on how involved Tiger was in the process and how much they thought about when designing it. He mentioned it was 4 ounces lighter than a previous Nike shoe (which seems like a lot), but I'm not sure if that was the Lunar Control.
I wonder if they sent out samples to product testers or just stuck with Tiger. There's a site where you can sign up to become a product tester for Nike, but the thing is for shoes, I think you have to be either a size 9 or 12-14 because those are the only sizes they make the samples in.
