Our Booties can be worn as primary footwear (with just bare feet) or as a shell (worn with something else inside them like a sock/slipper/leather shoe). The Booties are fleece-lined inside and coated nylon outside, making them wind and rain resistant. If the Booties are going to be worn in very cold weather, we suggest adequate layering inside the Booties; for example, you may choose to layer up with our Stonz Linerz, sheepskins slippers, or leather slippers for extra warmth.
The key with the Booties is assessing the weather you're about to be in and then layering up inside the Booties accordingly. Parents and caregivers are the best judge of the weather outside and the protection required for their children. The Booties are meant for all seasons; designed for flexibility in almost every outdoor weather condition!
