Well I don't have kids so I can't give any direct advice but I see a lot of anti-barefoot answers again! People, there are NO rules against bare feet in stores or even restaurants, that it is unhealthy and unsanitary is nothing but a myth. Please don't get your health education from a bunch of signs on store windows, but do a bit of real research on the matter! Going barefoot is healthy and comfortable, our skin was made to keep germs out & we're far less at risk from bare feet than from hands; especially kids who still are far more likely to stick their fingers in their mouths even when they aren't eating, but also adults will far easier transfer germs to our face/mouth where they can enter our bodies from our hands than from our feet. Any time you're opening doors, holding a hand rail, using a shopping cart, pushing buttons of elevators etc, or even using money that's been through dozens of hands, you're taking more risk than I do walking barefoot everywhere. And as long as you're warmly dressed on upper body & head, it's possible to keep feet warm even in the snow... I've done that... (no, they did NOT go numb, I know the difference between numb & warm :P). Sad to see so much bias against going barefoot in the US :(
Asker, please check the first link, it's a site for parents of barefoot children! I don't think they have specific winter outings but it's still a good place to visit.
