For the ones who will one day shape the future. The adidas NMD_R1 Shoes recapture the inventive spirit of the '80s, when wearable technology like wristband calculators and fitness trackers became realities. This version of the shoes is sized just for toddlers. They're made of lightweight mesh and are cushioned to keep first steps energized and comfortable. Elastic laces make it easy to go from play time to nap time.
