ThermoBall Traction Mule II Slipper - Kids'

What Our Gearhead® Experts Are Saying:

"These are kid-proof in the best way—warm, sturdy, and super easy to slip on. Parents love that the rubber sole works indoors and out, and kids love that they feel like puffy jackets for their feet. Heatseeker insulation really does keep toes warm, even on cold floors or snowy porch runs."

When cold floors and frosty mornings meet eager little feet, the ThermoBall Traction Mule II Slipper steps in with instant warmth. Built with a durable recycled ripstop exterior, these slippers handle indoor lounging just as effortlessly as backyard exploring or quick trips to the mailbox.

The Heatseeker insulation wraps growing toes in lightweight, reliable warmth, while the slip-on design gives kids the freedom to pull them on independently—no socks, no laces, no fuss. A grippy rubber outsole offers real traction on hardwood, sidewalks, or campground paths, making them far more versatile than the average slipper.

Soft, cozy, and tough enough for indoor-outdoor play, the ThermoBall Traction Mule II keeps kids warm and moving through winter’s chill.
