NPS is based in Wollaston, Northamptonshire, an area known for its shoe industry.

Boat shoe: Boat shoes (also known as deck shoes) are typically canvas or leather with non-marking rubber soles designed for use on a boat.

Gravati: Gravati is a family-owned company founded in 1909 that manufactures men's and women's dress shoes in Vigevano, Italy.  Although Gravati uses a variety of shoe construction methods, including Bologna and Goodyear construction, the majority of their production uses Blake construction.  The shoes are hand-crafted entirely within the factory by skilled artisans and technicians.  Every pattern of every Gravati shoe is hand-cut.  Unlike most modern shoe manufacturers, Gravati does not maintain stock—retailers must specify the patterns, lasts, leathers, soles, and construction methods that they want; and only then will the factory make the shoes.  Their production methods are typical of many upper-echelon shoemakers in that the uppers are cut (or clicked) and lasted and the shoes finished by hand, but that all sewing is done by machine.

Hoof boot: Hoof boots are commonly seen as a substitute to horseshoes, either as a backup for a thrown shoe when a farrier is not available, or as an alternative form of hoof protection for a barefoot horse.  Horse boots are used in all riding disciplines and are particularly popular for trail riding and endurance riding.  They are also used on horses in parades and on police horses who work on hard pavement.  Hoof boots may also be used when transitioning a horse from shod to unshod riding, or carried during a ride in case a horse throws a shoe.  In areas with persistently slippery conditions in winter, hoof boots are often used in combination with studs screwed into the soles.  This allows the horse to be ridden safely on slippery surfaces.  This must be done with a hoof boot with a sufficiently thick and inflexible sole to avoid bruising of the hoof sole.  Boots with soles that are too flexible are unsuitable for studding.
