The term "clog" refers to a type of shoe with a closed toe and an open or closed heel, traditionally made from wood or other materials. Crocs, on the other hand, are a specific brand of footwear known for their lightweight, comfortable, and waterproof design. Crocs are often referred to as "clogs" due to their similar shape, but they are made from a proprietary foam material called Croslite, which sets them apart from traditional clogs.
