Just doesnt appear that one of the design goals or intended uses was rough and tumble play. I returned and orderd the 18 to 24 month and those are perfect, they do fit a bit long but he has jo trouble walking in them and doesnt trip. diabetes & edema are the cause & nothing can be done about it! I was searching for a replacement and this one came up. So, really upset that I didnt get what I ordered. They run REALLY small. I do love these shoes! I havent had any problems walking around with them, but they can get very hot if the temperature goes up. Maybe, tighten up once again a week later if that makes you feel safer. So yes, I highly recommend these, and please note that I did NOT receive any discounted or reduced price to try and write a review.
