I am glad we bought these. I got them for my 6 year old who can tie his shoes a little bit, but not tight enough to really be effective. These are working well. Note 2 things. First, the package shows you should put the largest/widest ones at the end and the tightest ones towards your foot. That didn't work for us. He needs the full width ones next to his foot so he can get them on. Second, these are a little hard to work with at first. Know that it seems they will not break no matter how hard you pull on them. So if you are having trouble getting them in, don't be afraid to keep grabbing as much as you can and giving a good pull. Even when you need to take one out, that seems impossible, but if you just yank on them so hard you think they will break, they pop out.
