Our 1 yr old had started cruising a while ago. We moved recently to a house with all wood floors. With winter setting in, my poor boy could barely stand up with his socks. I did plenty (and when I say that, I mean weeks together) of research. My husband and I finally decided close to $40 was worth our money so our baby could walk. And, boy, does this do the job or what! It's snug. Doesn't come off no matter what. His feet are toasty. He's got big feet, so we got the 2-3 yr old size, and there's definitely room to grow, but I'd rather that, than a too-snug fit. Also, Amazon was wonderful about a slight problem we had. The sole had a very small tear in it, and I didn't think much of it initially. But it started to get bigger, and I couldn't imagine how I was going to mend it myself. They literally exchanged it the very next day. We don't think we'll use these outdoors, just so we can preserve it for as long as possible. But they really are worth the money spent. I bought a pair of Carter's slipper socks, and they did nothing for my son. I can vouch that Robeez really does do a stupendous job with the booties they make. Thank you, Robeez, and Amazon!
Had these for close to 3 weeks now, and there's absolutely nothing wrong with these booties :)
