My grandson is 13 months old and like all little ones, couldn't keep socks on for two seconds. A December baby and an early walker, he needed something that was not only durable, comfortable, warm, and non-slip, but that would also stay on without any fuss. The design allows them to fit for a good long while, and they're very affordable. I'm so glad I found these and didn't leave them in my cart for ages debating. I got the 2-pack thinking he could take a pair and leave one at Grandma's. I wrote his name on the bottoms of the pair he took, he loved them so much he wore the sharpie off in less than 2 weeks. His parents have told me several times that they love them, and it's super nice that the little guy wants to keep them on. So, I gave them both pair, and came back to grab one more to keep here. Anyway, they have been extremely useful for our little toddler and we can't recommend them highly enough! If you're debating like I did, let me assure you that once you get them, you'll wish you hadn't hesitated.
