Oh, patents! Perugia's super high heel


Copyright © Françoise Herrmann

In US2465817 titled High heel shoe, Perugia disclosed a comfortable, and aesthetically pleasing, 4-inch high heel shoe without the use of a platform to compensate for the increased height. 

The invention invoked a concave inner sole, designed to prevent the foot from slipping forward under pressure of the heel height. The concave inner sole thus replaced the need for what was perceived as unsightly platforms while still affording extra height, compared to the state of the art in the height of women’s shoes.

In US246817, the high heel and its concave inner sole were embodied in a pump, and described as applicable to other upper shoe designs such as Perugia's marketed, "mask mule" included as an illustration in this post. 

A patent drawing, showing the pump embodiment of the invention, extracted from US2465817, titled High-heel shoe, is also included.

Oh, patents! Perugia’s musical heel

Copyright © Françoise Herrmann


In, 1927, Perugia invented a musical heel enabling the person wearing them to make sounds with every step. However, this invention was designed with performance artists in mind, and especially circus performers, who might each have different musical shoes, and thus produce music together in various combinations.

The invention, disclosed in FR625731, consisted in a hollow and compressible rubber heel functioning as a compressible air chamber. That is, with every step the air contained inside the chamber of the rubber heel is described as compressed and forced through a sound-making instrument (10). The sound-making instrument is described as consisting in a small opening and tube equipped with a membrane that vibrates to produce a sound when air is forced through. Thus, the sound-making instrument within the heel is disclosed as both air and vibration driven, whereas the compression mechanism is variously described as consisting in a spring, that is gusseted or not. 

Two 1927 patent drawings, extracted from Perugia's musical heel patent, are included. Figure 2 shows the empty heel, and Figure 3 shows one embodiment of the invention with a gusseted spring and the small opening and tube equipped with a vibrating membrane.

Oh, patents! Perugia's replaceable heel


Copyright © Françoise Herrmann

One of Perguia’s famous heel inventions was disclosed in US2795866, titled Ladies’ shoes, granted in 1956, and assigned to Isaac Miller. This heel patent concerned a replaceable heel. The invention addressed the fashion-conscious need to change heels to match an outfit, or the need for comfort to better suit a particular purpose, such as  "hike or walk”.

The embodiment of the invention included a curved metal “tenon” and “mortise” slide, attached lengthwise on the outside of the shoe, under the arched and heel portions. The tenon served in this manner as a shank, and it was re-inforced by the metal mortise slide, attached to the shoe. A locking mechanism was also provided for the tenon and mortise system, in view of preventing the heel from slipping. Most importantly, the heel assembly system was designed so as to require no tools and no exertion when changing heels.


Patent figure drawings are included to the right, and below, a modern marketed version of the replaceable heel shoe.

Oh, Patents! Perugia’s heel construction

FR595482 - Fig. 1
Copyright © Françoise Herrmann
Many of Perugia’s patents are heel-related. This is probably because in 1925 Perugia actually changed the way women's heels were previously constructed.

FR595482 - Fig. 4
In the 1925 French patent, FR595482, Perugia disclosed the sheet metal housing of a shoe heel (Fig. 1), designed to receive two parts of a heel made of wood and assembled in a "T" shape (Fig. 4). This invention replaced the former method of heel construction consisting in nailing or gluing leather around a single block of wood, carved into the shape of a heel. The problematic situation consisted in the expense and time it took to carve the single piece of wood-block heel, and then to wrap it in leather, and to attach part of the shoe sole at the connection point with the rest of the shoe.

Perugia changed the former art, by designing a metal housing for two blocks of wood assembled as an angled “T” shaped heel (Fig 4). The metal housing could additionally be fashionably enameled to bypass covering it with leather. The empty spaces inside the housing could be filled with cork or other materials, and the metal housing was held together with metal threads or fasteners.

The invention thus afforded both a much lighter heel than single-block wooden heels. And, compared to a housing heel with no wood blocks inside, it also offered a more resistant heel as it still enclosed the wooden T-shaped blocks. The scope of the invention also extended to all sorts of heels, beyond women’s high heels.

FR608988 - Fig 4 
A year later, Perugia filed an improvement to his novel heel construction invention. This improvement, disclosed in FR608988, consisted in changing the ergonomic shape of the two pieces of wood, assembled as a “T” within the metal housing (Figure 4]. Essentially, the horizontal block of wood was fabricated in an augmented size, to provide more anchoring when attached to the heel part of the shoe, and the vertical block was more beveled to better accommodate the increased surface of the horizontal block and it's shape.

Both of these two early patents awarded in France to Perugia, in 1925 and 1926, were almost concurrently re-filed in the USA (as US1809918 and US1642889), in Switzerland (as CH124341 and CH118696), in Canada (as CA274538 and CA264938) and in Austria (AT108548 and AT106112), which suggests how important they were to the manufacture of shoe heels.

From then on, Perugia filed many more heel patents: design patents draping the metal housing “turban-style” (USD111857, USD112086 USD111858), and many additional utility patents such as the whimsical “music box heel” patent (FR625731) or a new heel height patent (US2465817), and a famous heel customization (US2795866) patent.

Oh, patents! Perugia superstar, FR utility patents

Copyright © Françoise Herrmann

Below, you will find a hyperlinked list of the patents that Perugia filed with patenting authorities at the French Ministries of Commerce and Industry, or Commerce and Energy, depending on the Administration in place, and now all stored at the INPI – Institut de la Propriété Industrielle in France -- just in case you had doubts about this shoe genius and how prolific an inventor in the domain of shoewear and shoe manufacture!

Just as a reminder, each of these 50 French inventions was filed and examined, and then judged patentable according to the three criteria of patentability: novelty, inventive step (no pun here) and usefulness (meaning with industrial application in Europe). Thus, each invention was not only a new improvement, product or process, it was also one that was non-obvious to those skilled in the art. Indeed, what is perhaps most extraordinary is that all of these previously non-obvious inventions were designed and commissioned for the comfort, beauty and glamour of women's feet, exclusively!

 exhibited in NYC in 1955
For a single individual, it is otherwise really quite uncommon to have invented so many new shoe manufacturing processes, materials and designs, in such a relatively short period of time, with a horrific interruption during World War II, which engulfed most of Europe from 1944 to 1948. 

As for Patents on the soles of your shoes… What a catch!

Oh patents! Perugia, superstar shoe designer

Copyright © Françoise Herrmann

André Perugia (1893-1977) was a famous, turn of the 20th century, shoemaker and designer. He was also Israel Miller's lifelong friend!

Perugia was born in France, of Italian shoemaker parents. He set up shop in Paris in 1909, where he sold handmade shoes. Perugia was a brilliant shoe designer and prolific inventor, with more than 100 registered patents, including dozens of US design patents and utility patents. Perugia also filed patents in France,  Germany, Canada, Great Britain, Switzerland and Austria!  

Below, you will find a list of André Perugia's timeless  US (only) Design patents, some of which were granted in batches with consecutive numbers. For example, six consecutive US Design patents were granted on March 16, 1937,  and five were granted on May 8, 1934.

The illustrations filed for each of Perugia's famous design patents are hyperlinked from the USPTO to the list of design patents below. Just click on the US Design patent number to see the registered drawings of the shoe design filed as part of the patent.  

For the definition of a design patent and differences compared to utility patents, please refer to the Patents on the soles of your shoes post on Design and utility patents: What’s the difference? In a nutshell: 
 “a “utility patent” protects the way an article is used and works (35 U.S.C. 101), while a "design patent" protects the way an article looks (35 U.S.C. 171).” [USPTO]
