A quick FYI for my fellow Card fans who are obsessed with Cards gear.
In my search for red shoes, I happened upon this site at Adidas where you can make custom shoes. You can add as much red, black and white as you want anywhere on the shoe. And the bonus is that you can add the Cardinal head logo to the back.
They cost around $110 after shipping and take around 4 weeks to get to you.
You can start making your own pair here. Adding the Cardinal head is under the Personalize > Personalization Logo section.
