A viral TikTok trend involves freezing shoes overnight in water containers and wearing them to slide down grassy hills like skis. The trend began with 18-year-old Carter Markie from Hawaii and has since been replicated by dozens of creators. Crocs or foam clogs work best as they float in water and freeze on top, though the stunt carries risk of ankle, shoulder and back injuries.
