Gaiters are garments worn over the shoe, reaching from the instep to above the ankle or to mid-calf or knee.  Traditionally they were made of leather, wool or cotton.   

Gaiters formed a part of the everyday clerical clothing of bishops and archdeacons of the Church of England until the middle part of the twentieth century. Ecclesiastical gaiters were made of black cotton, wool or silk, and buttoned up the sides, reaching to just below the knee where they joined with black breeches.
