Goodyear Welt
A Goodyear welt is a strip of leather, rubber, or plastic that runs along the perimeter of a Shoe#Shoe_construction, shoe outsole. The machinery used for the process was invented in 1869 by Charles Goodyear Jr., the son of Charles Goodyear. It has been noted by historians that Goodyear was a frequent visitor to the shoe factory of William J. Dudley, founder of Johnston & Murphy, where early work on sole stitching equipment was performed. Construction "Goodyear welt construction" involves stitching a welt to the upper and a strip of preformed canvas like a "rib" that runs all around and bottom (known as "gemming") cemented to the insole of a shoe as an attach-point for the outsole or midsole (depending on the Goodyear welt variant). The space enclosed by the welt is then filled with cork (material), cork or some other filler material such as foam (usually either porous or perforated, for breathability and cushioning), and the outsole is both cemented and stitched to the welt.

Leather
Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators. Leather can be used to make a variety of items, including clothing, footwear, handbags, furniture, tools and sports equipment, and lasts for decades. Leather making has been practiced for more than 7,000 years and the leading producers of leather today are China and India. Animal rights groups claim that modern commercial leather making and the consumption of its products is unethically killing animals. According to the life-cycle assessment (LCA) report for the United Nations Industrial Development Organization, 99% of the raw hides and skins used in the production of leather derive from animals raised for meat and/or dairy production. Critics of tanneries claim that they engage in uns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...

Plastic
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1, ...

Shoe
A shoe is an item of footwear intended to protect and comfort the human foot. They are often worn with a sock. Shoes are also used as an item of decoration and fashion. The design of shoes has varied enormously through time and from culture to culture, with form originally being tied to function. Though the human foot can adapt to varied terrains and climate conditions, it is still vulnerable to environmental hazards such as sharp rocks and temperature extremes, which shoes protect against. Some shoes are worn as safety equipment, such as steel-toe boots which are required footwear at industrial worksites. Additionally, fashion has often dictated many design elements, such as whether shoes have very high heels or flat ones. Contemporary footwear varies widely in style, complexity and cost. Basic sandals may consist of only a thin sole and simple strap and be sold for a low cost. High fashion shoes made by famous designers may be made of expensive materials, use complex constr ...

Charles Goodyear
Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844. Goodyear is credited with inventing the chemical process to create and manufacture pliable, waterproof, moldable rubber. Goodyear's discovery of the vulcanization process followed five years of searching for a more stable rubber and stumbling upon the effectiveness of heating after Thomas Hancock. His discovery initiated decades of successful rubber manufacturing in the Lower Naugatuck Valley in Connecticut, as rubber was adopted to multiple applications, including footwear and tires. The Goodyear Tire and Rubber Company is named after him. Early life Charles Goodyear was born on 29 December 1800, in New Haven, Connecticut, the son of Amasa Goodyear, and the oldest of six children. His father was a descendant of Stephen Goodyear, succ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Fluevog
John Fluevog (born 1948) is a Canadian shoe designer and businessperson. In 1970, he and a co-worker Peter Fox began their own shoe store in Vancouver. The shoes are described as "progressive, art deco" inspired. The company claims that the shoes are designed in Vancouver, and manufactured in Portugal, Mexico, Peru, China and Vietnam according to the company's website.

Cork (material)
Cork is an Permeability (earth sciences), impermeable buoyancy, buoyant material, the Cork cambium, phellem layer of bark (botany), bark tissue that is harvested for commercial use primarily from ''Quercus suber'' (the cork oak), which is native to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobic substance. Because of its impermeable, buoyant, elastic, and fire retardant properties, it is used in a variety of products, the most common of which is wine stoppers. The Dehesa (pastoral management), montado landscape of Portugal produces approximately half of the cork harvested annually worldwide, with Corticeira Amorim being the leading company in the industry. Cork was examined microscopically by Robert Hooke, which led to his discovery and naming of the cell (biology), cell. Cork composition varies depending on Geography, geographic origin, climate and soil conditions, Genetics, genetic origin, tree dimensions, age (virgin or reproduction), and gro ...

Last
A last is a mechanical form shaped like a human foot. It is used by shoemakers and cordwainers in the manufacture and repair of shoes. Lasts typically come in pairs and have been made from various materials, including hardwoods, cast iron, and high-density plastics. The term is derived from the Proto-Germanic *''laistaz'' ("track, trace, footprint"); cognates include Swedish ''läst'', Danish ''læste'', German ''Leisten''. Production Lasts come in many styles and sizes, depending on the exact job they are designed for. Common variations include simple one-size lasts used for repairing soles and heels, durable lasts used in modern mass production, and custom-made lasts used in the making of bespoke footwear. Though a last is made approximately in the shape of a human foot, the precise shape is tailored to the kind of footwear being made. For example, a boot last would be designed to hug the instep for a close fit. Modern last shapes are typically designed using dedicated compu ...

Contact Cement
Impact glue, contact glue or neoprene glue, is a type of glue, used mainly to glue plastic foams, laminates, metal panels, etc. . It also allows the mounting of supports of different types (metal on wood, cork on plaster, wood on cement, etc). Contact-type adhesives do not exclusively designate neoprene adhesives, but also all other adhesives characterized by high instant adhesion. Special features Impact glue has a high adhesive capacity, and it is very resistant, it must be applied in thin layers. ''Impact adhesives'' are used in strong bonds with high shear-resistance like laminates, such as bonding Formica to a wooden counter, and in footwear, as in attaching outsoles to uppers. Natural rubber and polychloroprene (Neoprene) are the most commonly used contact adhesives. Both of these elastomers undergo strain crystallization. Contact adhesives must be applied to both surfaces and allowed some time to dry before the two surfaces are pushed together. Some contact adh ...
