You're never too young for a pair of shell toes. The Superstar 360 Infant Boys by adidas Originals turn the famous shell-toe trainer into a flexible slip-on. A stretchy neoprene-like upper and foam sockliner make them comfortable to wear. These flexible-slip on shoes are soft all around and easy to slide on and off little feet. Fitfoam sockliner, made of a visco-elastic rebound foam, contours to your little one's foot like a custom mould.
