Nike’s Back to the Future trip has been a big success. The topic is burning up the blogosphere, sports blogs, especially and, of course, Twitter. Furthermore, there are reports are coming in of astronomical prices being paid for Nike’s futuristic high-top, and when I say astronomical, I’m talking spending in excess of $10,000 for one pair.

As the previous article demonstrated, the shoes are going anywhere from almost $4000 up to five-digit amounts, but thanks to the spending power of British rapper named “Tinie Tempah” (Tiny Temper, I suppose). Tinie, according to the stalwart journalists at TMZ.com, is reported to have paid $37,500 for a pair of Marty McFly’s shoes.

I say again, someone paid almost 40 grand for a pair of futuristic-looking shoes that don’t even have the power laces system as a feature. I don’t know about you, but if I had that much money to dispose of, it’s doubtful a pair of shoes I’d rarely, if ever, wear would be where my money goes.

Whatever the case, I’m sure the Michael J. Fox Foundation, one that battles Parkinson’s Disease, is thankful for Tempah’s generosity. Speaking of Fox, he was on David Letterman the other night, demonstrating his shoes for the Dave and the audience:

With all the discussion going on about the shoes, naturally, it became a trending Twitter topic, under the “Back to the Future” hashtag. Needless to say, there was a lot of “do want” types of responses, as well as people discussing the price Tempah paid for his pair:

Unfortunately, however, the power laces are not available:

But people do still want them:

Well, Betty, they can be yours for a starting big of around $4000. If they had the power laces, I’d be bidding right now.

All donations for the Air Mag shoes will be matched by Google’s Sergey Brin (up to $50 million). This vicariously means that Brin, thanks to the buying power of Tinie Tempah, will be paying almost $70,000 for a pair of shoes he won’t even get to own.
