This thread is an example that americans have a very dofficult time when it comes to clothing. Sports shoes, these white, bulky bottom, etc.. they are worn by, as Moen said - people in the wheelchair, or old fellas with cargo shorts, etc.. (we talk - public wear here, afaik).
And brands, prices, etc... I'd buy a 30$ shoes instead of 3000$ if these would be the ones I like. It's not the case with some people tho'.. Some assume - if the shoes,shirt, pants are expensive (and of a known brand) - they MUST be fashionable and stylish. Lol.. I would wear converses over these horrible looking leather shoes with red shades any day, and I couldn't care less about the price.
But - let's not forget taht this is a board of bodybuilders.. This group of people has been known to be a horrible dressers for quite some time already (too lazy to post the example pics), and I notice that not just in US, but here in Europe too, to some extent (amongst other bodybuilding fellas).
These t-shirts are cool. It's not just about the patterns/pictures, etc.. but about the design of how they fit a body too. These should look really god on an athletic body.
