These work. I bought the child size, and only ended up needing the 4 smallest sizes for each shoe for my Toddlers size 9T shoe. I don't mind the silicone construction, though I question how well it will hold up as I see stress marks appearing in the material as they stretch. Also, the fixtures at the end that thread through the eyelets are not downsized for a child sized shoe. I had to insert my jewelry needle nose pliers through the eyelet and gently stretch it open wider before I could squeeze these through. Still, one of the fixtures tore as I gently pulled as per instructions. It would be better to have a plastic or metal toggle at the end. All in all, they look great and are working well for now. I will update if they wear out more quickly than I think is reasonable.
