Can you imagine yourselves wearing sport shoes but you do not need to face any difficulties in lacing the shoes? Now, Nike has introduced self-lacing shoes with high technology that enables the shoes to lace itself.
Nike self-lacing shoes or adaptive lacing shoes are when you step in the shoes and your heel will hit a sensor, the system will automatically tighten. There are two buttons on the sides of the shoes that will allow you to adjust whether you want to loose or tight the laces. Theoretically, the laces will be held in a position where it will prevent the laces from coming undone when you're running it doing any other sports.
If you are wondering about the battery of these self-lacing shoes, there will be a glowing component built in the sole that acts as a wireless charging point and there are also LEDs at the back to indicate how much charge remains so that the user may be able to charge it when it is on low power. The shoes will need to be recharged once in the fortnight.
