No risk of losing their LEGO® bricks with these infants' adidas shoes, because they stay laced onto their feet. The colourful trainers have a durable textile upper with hook-and-loop straps for a snug fit and easy on-and-off. Play time is all the time with them. This product is made with Primeblue, a high-performance recycled material made in part with Parley Ocean Plastic. 50% of the upper is textile, 75% of the textile is Primeblue yarn. No virgin polyester.
