I received a pair of these as a gift for our winter baby, and once I tried them, I never put socks on again!  These are soft, warm, cute, and don't fall off, even with all the kicking.  So when she outgrew the 3 month size, I bought the 6-month size, which she is again wearing every day.  Seems pricey for a baby booties, but one pair is enough- they don't really get dirty unless she manages to spit up on her feet (it did happen once) so a weekly wash is fine.  Highly recommend!
