Moccasin construction builds shoes by wrapping upper material up around the bottom of the foot, then closing over the top by stitching to a separate upper piece, or vamp plug, above the ball and sometimes the instep.
Moccasin construction was historically characteristic of Native American shoemaking, often with brian- and smoke-tanned deerskin.
Moccasin construction is not to be confused with moccasin toe style, which builds a vamp of two pieces, or imitates their joint with a stitch line, but stitches the upper to a separate insole.
Manufacturers often produce moccasins as house slippers, with or without adhered outsoles. A few manufacturers, such as Russell Moccasin, use Moccasin construction to build outdoor boots.
