The term 'KIND OF SOCK' can be broken down into three different crossword solutions: CREW (4 letters), ANKLET (6 letters), and KNEEHIGH (8 letters). A CREW sock is a type of sock that typically covers the ankle and calf, and is often worn with sneakers or other casual shoes. An ANKLET is a short sock that only covers the ankle, and is usually worn with dress shoes or sandals. Kneehigh socks are longer than CREW socks, and cover the calf and sometimes even the knee. They are often worn with boots or other formal shoes.
