Converse All Stars, also known as Chuck Taylors, Chucks, Cons, or All Stars, are sneakers manufactured by the American brand Converse. The shoe consists of a stitched upper portion and a toe cap and outsole usually made of rubber. The vulcanized shoemaking process involves bonding and trimming the toe cap part, attaching the rubber outsole, and heat-curing the rubber sole. While the toe cap is typically made of rubber, some users have noted that the plastic around the toe area of certain models, like the Chuck 70s, is very hard and taller, making the toe area feel narrow and squishy.

What You'll Learn
The vulcanized shoemaking process
Vulcanization is the process of transforming natural rubber into a more durable form by curing it. This process was first used by Marquis Mills Converse in 1908 when he opened the Converse Rubber Shoe Company, a manufacturer of vulcanized rubber-soled footwear. Vulcanization involves heating raw rubber to around 170˚C, which cures it and makes it less sticky, allowing it to bond with surrounding materials. This process replaces cement or glue and results in a strong, flexible material suitable for footwear. Vulcanized rubber is also anti-skid, wear-resistant, and less likely to age and crack.

Rubber outsole attached
Converse All Stars are made using the vulcanized shoemaking process. Marquis Mills Converse opened the Converse Rubber Shoe Company in 1908, and the company began manufacturing vulcanized athletic shoes for tennis and other sports in 1915. The vulcanized shoemaking process involves attaching the rubber outsole to the upper part of the shoe before the rubber is heat cured. The entire shoe is then heated in a vulcanizing oven at around 170°C. This process is different from the equipment and methods used to make cold cement shoes.
The Converse All Star is a double wrap shoe. The first step in the vulcanized shoemaking process is the bonding and trimming of the toe cap part. The upper then receives a pre-wrap before the rubber outsole is attached. The pre-wrap is a thin layer of rubber that covers the upper and wraps around the bottom edge. After the pre-wrap and outsole are bonded and the outer wrap is applied, the final operation attaches the textured toe foxing tape and rear “license plate” heel logo part. These parts cover the seams of the outer wrap.
The toe cap is a distinctive feature of the Converse All Star shoe. In 2014, Converse filed a lawsuit against 31 companies for allegedly infringing on its sneaker style's bumper toe, striped midsole, and toe cap. The brand argued that these companies were violating a common-law trademark by importing "knockoff" sneakers with similar elements. Several companies settled with Converse, and a judge ruled that several brands were indeed violating Converse's outsole design trademarks.
The Chuck Taylor All Star '70, launched in 2013, featured a higher rubber midsole and foxing, a smaller toe cap, and a one-piece rubber bottom sole. The toe area of the Chuck 70s is narrower than the normal Chucks due to the thicker and higher rubber. The rubber toe cap of the Chuck 70s is also noted to be harder than the original Chucks.

Toe cap part
The toe cap is an integral part of the Converse All Star shoe design. The shoe was initially developed as a basketball shoe in the early 20th century, and its design has remained largely unchanged since its introduction. The toe cap, along with the outsole, is usually made of rubber. The vulcanized shoemaking process involves attaching the soft white rubber outsole to the shoe upper before the rubber is heat cured. The entire shoe, with the sole parts attached, is then heated to around 170˚C in a vulcanizing oven.
The toe cap is a distinctive feature of the Converse All Star, and the brand has taken legal action against companies allegedly infringing on its sneaker style's bumper toe, striped midsole, and toe cap. In 2014, Converse filed a lawsuit against 31 companies, including major retailers such as Walmart, Skechers, and Ralph Lauren. The International Trade Commission preliminarily ruled in Converse's favour, finding that several brands were violating their outsole design trademarks.
However, in 2016, the International Trade Commission ruled that Converse's alleged trade dress for the midsole design of a combined toe cap, toe bumper, and stripe was not entitled to trademark protection under common law, invalidating Converse's federal trademark registration.
The toe cap has undergone some modifications over the years. The Chuck Taylor All Star '70 model, released in 2013, featured a smaller toe cap compared to the standard Chuck Taylor All Star. The 2015 Chuck Taylor All Star II also featured a slightly smaller toe cap, along with other design changes such as thicker canvas and cushioning.
The toe cap area of the Chuck 70s has been noted to be narrower than the normal Chucks, with some users reporting discomfort due to the tighter fit. The rubber in the toe area of the Chuck 70s is also described as thicker and taller, making it less likely to stretch over time.

Rubber doesn't stretch
Converse All Stars are manufactured using the vulcanized shoemaking process. Marquis Mills Converse opened the Converse Rubber Shoe Company in 1908, and the company began manufacturing vulcanized athletic shoes for tennis and other sports in 1915. The vulcanized shoemaking process involves bonding and trimming the toe cap part, attaching the rubber outsole, and bonding the pre-wrap and outsole before applying the outer wrap. The vulcanizing process requires heating raw rubber to cure it, and the shoe is heated to around 170˚C.
The toe cap and outsole of the Chuck Taylor All-Stars, also known as "Chucks", are usually made of rubber. The Chuck Taylor All Star '70 model features a higher rubber midsole and foxing, and a smaller toe cap. The rubber is quite thick, and the canvas extends into the toe as well. The toe area of the Chuck 70s is much narrower than the normal Chucks due to the rubber coming up higher and being thicker.
The rubber in the toe area of the Chuck 70s is unlikely to stretch because it is very hard and taller, and rubber does not stretch like leather or other materials. The plastic around the toe area of the Chuck 70s is also hard and taller, making it even less likely to stretch. While some users have reported that the toe area may stretch a little, it is not expected to stretch significantly.
To make the toe area of the Chuck 70s more comfortable, some users have suggested using shoe stretchers or sizing up by half a size. Removing the comfort insole and replacing it with a thinner one can also help improve the fit.

Converse's trade dress
The vulcanized shoemaking process used to make Converse All Stars was pioneered by Marquis Mills Converse, who opened the Converse Rubber Shoe Company in 1908. The company initially manufactured vulcanized rubber-soled footwear and later expanded into athletic shoes for tennis and other sports. In 1917, the Converse All-Star basketball shoe was introduced, and it became popular with the support of basketball player and ambassador, Charles H. "Chuck" Taylor.
The trade dress of the Converse All Star shoe has been the subject of legal disputes, with Converse filing complaints against companies allegedly infringing on its design. In 2014, Converse filed a complaint with the International Trade Commission (ITC) to stop the importation of shoes by over 25 companies in violation of the Tariff Act of 1930. The Federal Circuit Court of Appeals reversed a decision from the ITC in 2018, acknowledging that product design trade dress can never be inherently distinctive but remanding the case for further review.
The outcome of these cases has implications for the legal landscape of trademark law and the enforcement of product design trade dress in the United States. The Federal Circuit has clarified that the presumption of "acquired secondary meaning" associated with registration does not apply retroactively and is only effective from the registration date. This means that for infringements that occurred before the registration date, Converse must establish that its trade dress had acquired distinctiveness or secondary meaning prior to registration.
