Black shoes can be worn with khaki pants. Black and brown are neutral colors that can be mixed together, and shoes of both colors are a good match for khaki pants.
Khaki pants work well with sport coats or blazers. Shoes that match khaki pants include loafers, oxfords and leather cap toe lace up shoes. Socks should typically match the pants in color, but with khaki pants there is an exception and brown socks should be worn instead. Khaki pants were originally worn by members of the British military who were stationed in sandy wastes, because the color was an effective camouflage. After World War 2, khaki pants were sold to civilians.
