Tmnt by Striderite made to play shoes size 1

My tmnt obsessed son loved these until he outgrew them. They are a size 1 but the tag is no longer legible. Some signs of wear and tear from repeated putting on and taking off, as shown in close up picture of the openings. May also have portions of paint missing from being scuffed off from play. Pictures show all pretty clearly. Still much life left to them. They are washable. I did not run them through the machine. I always hand washed and wiped down. Soles are great as is the Velcro closure. Perfect for the next tmnt fan!
