Shoe maker Nike has announced its first self-lacing basketball shoes.

The 'Adapt BB' shoes can be adjusted using a person's smartphone.

The shoes will remember, through an app, how tight or loose a user prefers their footwear.

It also has different settings for different situations - like warm-ups, game play and resting.

When someone steps into the shoe, a custom motor and gear train senses the tension needed by the foot and adjusts accordingly.

The underfoot lacing is able to pull 32 pounds of force (roughly equal to that of a standard parachute cord) to secure the foot throughout a range of movement.

That is where the 'brain', or FitAdapt technology, kicks in.

By manual touch or by using the Nike Adapt app, people can input different fit settings depending on different situations.

He said: "Shoes in our Nike Adapt platform - of which Nike Adapt BB is the first - can update and evolve after purchase, letting consumers opt in to provide you with new services and features through smartphone-like technology.

"In other words, we've finally added firmware to footwear, letting us continuously improve the product you've already bought, responding as need be to changing preferences and environments."

"For most footwear out there, buying the shoe is the end of a transaction. But here, buying the shoe is just the beginning."

The shoe, which is set to go on sale in February, went through several tests - including impact tests, intense temperatures, end-of-life tests that lasted tens of thousands of cycles long, and waterproof tests to simulate the sweatiest feet.

But the company said the ultimate stamp of approval "still needed to come from players" in sport.

The Nike design team invited a group of professional players, including Jayson Tatum of the Boston Celtics, for a run of workouts and pickup games.
