These sneakers have become the most expensive ones ever sold at auctions. They have built-in pressure sensors. When a person puts on shoes, the sensors are triggered, and a special mechanism tightens the laces in the shape of the foot. On the outside of the sneaker there are buttons that can be used to adjust the tightening force if the automatic fails.
The proceeds will go to the Michael J. Fox Foundation to find a cure for Parkinson's disease. The famous actor who played Marty McFly in three Back to the Future films himself suffers from this terrible disease. In the next two months, two more similar auctions will take place - in London and New York.

The technology used in the sneaker is called HyperAdapt, and Nike plans to incorporate it into mainstream athletic shoes. The first sneakers of this type will go on sale in November and will be available in limited quantities, exclusively for users of the Nike + fitness app.>
