Sportswear firm Nike launched a series of new products including self-lacing shoes, transparent air-filled soles and soccer cleats made from a polymer that prevents mud from sticking to the sole at a glitzy event in New York on Wednesday (March 16) .
"You take the shoe you just slide it on, when your heel hits the sensor it will automatically close and adjust to a comfortable fit. Then if you want further adjustment you press the tighten button or you press the loosen button, you go about your day, anytime throughout the day you feel uncomfortable you adjust it and then when you're ready to get out of it, you press and hold the loosen button for two second and you're out and it's ready to go the next time you're ready," Nike's Tiffany Beers explained.
