In my list of sports brands, Puma is #1 and always will be.
The only reason I buy Reebok is because US Pro Football Jerseys are Reeboks and formed using Reebok's Patented fabric processing and hold up much better then any other pro sport uniform. Im sure most of you Football players will agree with me on that. I mean, I have a Tiki Barber jersey from back in the day, I wear it all the time and its the best quality ever.
I think Reebok is underdeveloped and sold to a audience geared toward Tennis players (as their shoes are based on the sport). If they can expand thier influence im sure they'll be just as good as Nike or Adidas, trusting they do a good job.
