What Our Gearhead(R) Experts Are Saying: "These have become my post-ski go-tos. They're super easy to slip on after a long day in boots, and the OOfoam footbed feels amazing on sore feet. The insulation is shockingly warm and the sole has enough grip to walk around the lodge or even outside."When our winter days wrap up, we slip into the OOcoozie Thermo Mule to keep recovery rolling. OOFOS built this insulated mule to bring their signature comfort into colder seasons. It's warm, supportive, and made for movement between indoor comfort and wintery sidewalks. Designed with OOfoam technology, the OOcoozie Thermo reduces stress on our feet, joints, and lower back. Add in a layer of lightweight Primaloft hi-loft insulation and a modern mule silhouette, and we're set for recovery with warmth and style. This is active recovery, evolved for winter.
