Shoes or Socks?

Alina

FTM - might be a stupid question but whatever

My son is 12 months old this month, doesn't walk yet so he doesn't wear shoes. But we love in MN where it gets really cold, so whenever we are out and about I just double up on socks for him. I guess my question is, should I start putting on shoes when we go out or is doubling socks okay?
