Can you imagine a pair of shoes that could tie themselves? All you would have to do is to put them on and push a button. Well, this idea is becoming a real reality. The shoe company Nike created the self-tying shoe! This idea first came from the movie Back to the Future II, Nike has been working for years to create a shoe that can do this in real life. They have finally done it with Nike HyperAdapt 1.0.
So how do they work? According to Nike, the shoe is “powered by an underfoot-lacing mechanism (脚下系带装置)”. This is kind of like a small motor (发动机) that has the power to lace the shoes. All the wearer has to do is to put them on, and at first, the shoes are very loose (松的). But then you can push the “+” button (按钮), and the shoes will tighten to be the perfect fit for the wearer. To take them off, all you have to do is to push the “－” button, and the shoes will be easily off.
They haven't been released to the public yet, and the cost of the shoes is still unknown. But you might be able to get a pair of your own closer to the holiday season this year.
