Nike Air Mag shoes on eBay now, Back to the Future but not to Britain

The Back To The Future Nike Air Mag shoes are now on eBay and already promising serious money for charity -- but they're only on sale to American bidders. Short of jumping in your DeLorean and blasting through time and space to the other side of the Atlantic, is there any way of getting hold of Marty McFly's trainers?

The sneakers are only available to US Back to the Future fans "because of individual country regulations governing the manufacture, distribution and/or sale of products containing batteries and other electronic components," eBay says. They light up, which apparently is going to be big in 2015. Sadly the shoes don't also lace themselves like in the film.

There are a number of services that furnish you with a US address to order stuff from the States, including BundleBox, SkyBox, MyUS and Shipito. Results may vary, so try these services at your own risk -- have you used these services to get your Stateside swag? Let us know in the comments section below.

The Nike Air Mag shoes are available in sizes 7-13 -- that's US sizes, so if you're a British bidder and you want to actually wear yours then knock a size off for your plates. Bids are currently around $5,000, but hey, postage and packing is free.

The proceeds of the auction will go to the Michael J Fox Foundation, a charity started by the Back to the Future and Teen Wolf star to fight Parkinson's disease. The Canadian actor was diagnosed with Parkinson's in 1991.

Google founder Sergei Brin and his wife Anne Wojcicki, biologist and founder of genetics company 23andMe, have agreed to match the money raised from auctions, with a possible $50m going to the Parkinsons charity -- so don't hold back with the bids, folks.

A total of 1,500 pairs will be auctioned, in batches of 150 per day until 18 September. Don't worry if you can't get hold of a pair, because you can always get yourself a pair of CNET UK, Facebook or Angry Birds shoes.
