I need suggestions of flexible shoes/socks that are good for a non-walker. I wouldn't normally put a non-walker in shoes at all, but I need something warmer than socks and that he can't easily pull off -- it's much too cold to be barefoot!
Yep, what Aimee said! This is the second kid I've had in those types of shoes, and they're great for keeping socks on.
Also, I love the Hanna Andersson Swedish Moccasins. I bought a knock-off pair for DD2 at Target this year, and we've got a couple of the actual Hannas that were hand-me-downs from my step-mom.
I love the Nowali moccasin shoes, also from Sweden. Years ago I watched my brother buy them in every size for his daughter, and now we are finding them to be fantastic for our little guy, chubby feet and all. As for socks, I bought some Robeez socks when they are were on Babysteals and they stay on like they are glued! They have extra elastic around the ankle and it really works.
