Here's what other sites are saying:
The Molehill Kid's Down Mule Slippers (for Infants, Toddlers, Juniors, and Youth) are down-filled gear for warm feet. These low-cut mules use waterproof breathable exterior fabric, luxurious fleece linings, tough 600 denier polyester soles with "gripper" dots, and are filled with warm light-weight down. These are the warmest, most comfy camp booties and slippers available. Great for around the tent or around the house.
