In the classic time-travel film Back To The Future II, Marty McFly wears a very distinctive pair of sneakers. In 2011, Nike introduced the Nike Air Mag sneakers as a limited edition product – and wowed the film's fans by revealing they were an exact replica of Marty's iconic shoes; and that the proceeds from each pair sold would go directly to the Michael J. Fox Foundation, dedicated to finding a cure for Parkinson’s Disease. But there was something missing.

Marty's shoes in Back To The Future II had a cool and unique technology called "Power Laces", which were self-tying laces that meant your shoes would effectively tie themselves the moment your feet settled into them. Many fans loudly decried their absence from the otherwise accurate homage of the Nike Air Mags – but surely such technology was pure fiction, right? According to Nike designer Tinker Hatfield, not any more!

Starting 2015, Nike intends to bring to market shoes with the iconic self-tying Power Laces as designed by Nike's own shoe designers. That timing couldn't be more perfect, as canonically the power-lace-equipped shoes of the classic film were actually said to be introduced in 2015, making a perfect example of art imitating life – one can't help but wonder if Nike have chosen to deliberately delay the launch to fit the events of the film. It's unclear whether the laces will appear on an updated version of the Nike Air Mag or on a new product entirely – which also means we don't yet know what the Power Laces will cost. So, what would YOU pay for shoes that tied themselves?
