The softest all-year-round indoor & outdoor booties for your little one. Think of these as socks or slippers for baby to wear around the house. Best for pre-walkers and walkers thanks to the anti-slip grip soles. When it's time to go outside, slip them on, bundle baby in their 7AM footmuff, and those little toes will be as warm as can be on your winter time walks.
