put them on and push a button. Well, this idea is becoming a reality. The shoe
company Nike created the self-tying shoe! This idea first came from the film
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.

mechanism(脚下系带装置) small motor that has the power to lace the shoes, All you have to
do is put them on, and at first, the shoes are very loose(松的). But then you can push the "+" perfect fit for you. To
take them off, all you have to do is push the "-" button, and the
shoes will be easily off.
