During Back To The Future II, Marty McFly, played by Michael J. Fox, puts on a pair of Nike High Tops that automatically tighten and adjust to fit his feet - using so-called power laces. Nike released a limited range of McFly's Nike MAGs with manual laces in 2011, and now designer Tinker Hatfield has revealed the power laces will arrive in 2015. Hatfield made these comments because 2015 was the year Back To the Future II was set in. Speaking at the Jordan Brand Flight Lab in New Orleans Hatfield told Sole Collector: 'Are we gonna see power laces in 2015? To that, I say yes!'Rumours about the technology have been circling since 2010 when Nike applied for a patent for 'automatically lacing trainers.'It said: 'The automatic lacing system provides a set of straps that can be automatically opened and closed to switch between a loosened and tightened position of the upper.'The article further includes an automatic ankle cinching system that is configured to automatically adjust an ankle portion of the upper.’The Back To The Future-inspired Nike MAG range was then launched in 2011.Only 1,500 models of the High Tops were made, and every pair was auctioned off on eBay.A total of $6million (£3.5million) was raised from the sales of these shoes, and all the proceeds went to the Michael J. Fox Foundation for Parkinson’s Research.San Francisco-based inventor Blake Bevin has already created her own self-tying laces, a prototype which she says will 'tide you over until Nike comes out with something more polished.'Using an Arduino microcontroller, Bevin fitted a sensor to a Nike High Top.When a person steps into the shoe, a force sensor reads the pressure of their foot and activates two servo motors, which apply tension to the laces, tightening the shoe.A touch switch can be used to reverse the servos.(dailymail.co.uk) ANN.Az
