The term 'KIND OF SOLE' can be broken down into three crossword solutions: Dover (5 letters), Crepe (5 letters), and INNER (5 letters). Dover sole is a type of flatfish found in the English Channel and North Sea. It is a popular fish for cooking, as it has a delicate flavor and texture. Crepe soles are thin, flexible rubber soles that are often used on shoes and boots. They provide good traction and are lightweight. INNER soles are removable insoles that are placed inside shoes to provide cushioning and support. They are usually made from foam or leather and can be replaced when they become worn out.
