Under Armour HOVR Machina 2 Women's Running Shoes - AW21

Like new! Online description says: "UA HOVR Machina 2 is more than a running shoe. Yes, it gives you energy return and the speed of a Pebax propulsion plate, but it also coaches you in real-time to help you run better when you connect them to UA MapMyRun" I scanned the data matrix and it took me to a phone number; not sure how the technology in these shoes work!
