The sewing machine was introduced in 1846, and provided an alternative method for the mechanization of shoemaking. By the late 1850s, the industry was beginning to shift towards the modern factory, mainly in the US and areas of England. A shoe stitching machine was invented by the American Lyman Blake in 1856 and perfected by 1864. Entering in to partnership with McKay, his device became known as the McKay stitching machine and was quickly adopted by manufacturers throughout New England. As bottlenecks opened up in the production line due to these innovations, more and more of the manufacturing stages, such as pegging and finishing, became automated. By the 1890s, the process of mechanisation was largely complete.

All shoes have a sole, which is the bottom of a shoe, in contact with the ground. Soles can be made from a variety of materials, although most modern shoes have soles made from natural rubber, polyurethane, or polyvinyl chloride (PVC) compounds. Soles can be simple — a single material in a single layer — or they can be complex, with multiple structures or layers and materials. When various layers are used, soles may consist of an insole, midsole, and an outsole.

There are a wide variety of different types of shoes. Most types of shoes are designed for specific activities. For example, boots are typically designed for work or heavy outdoor use. Athletic shoes are designed for particular sports such as running, walking, or other sports. Some shoes are designed to be worn at more formal occasions, and others are designed for casual wear. There are also a wide variety of shoes designed for different types of dancing.

Dress shoes are characterized by smooth and supple leather uppers, leather soles, and narrow sleek figure. Casual shoes are characterized by sturdy leather uppers, non-leather outsoles, and wide profile.

Other animals, such as dogs and horses, may also wear special shoes to protect their feet as well.
