However, Onitsuka Tiger decided that they weren’t happy with the name and once again made a change, this time looking to opt for the name ‘Aztec’, taking its inspiration from ancient Mexican history during the Aztec era. Despite the sneaker receiving its third name in two years, Onitsuka ran into further troubles, this time from one of their competitors, adidas. Despite the name change, Onitsuka Tiger does still use the ‘Mexico’ name in their ‘Mexico 66’ running sneaker, perhaps a nod to the original 1966 TG-24. The following year, at the Chicago Sporting Goods Association, Nike officially released three silhouettes to launch their new brand. The three silhouettes included the Marathon, Boston and the Cortez. At this time, Nike then released an advert for the Nike Cortez that included what they called ‘The Cortez Story’, which completely cut any mention of their previous partnership with Onitsuka Tiger. It was also here, that Nike released the first leather version of the Nike Cortez. On September 29, 2007, Onitsuka passed away from heart failure at a hospital in Kobe, Japan. The quote “if you fail, keep going until you succeed” is one way to describe how Mr. Onitsuka lived his extraordinary life. He was 89. Kihachiro Onitsuka’s 100th birthday, 2018.

In remembrance of Onituska, ASICS released “100th Birthday Commemorative” models on May 29, 2018. The products were designed with a sunflower that Onitsuka painted. This line includes the ASICS’ GEL-QUANTUM™ 360 KO100, the ASICS Tiger GEL-MAI™ KO100 and the Onitsuka Tiger CORSAIR™ KO100 running shoes, as well as a line of apparel. The future of ASICS marks the 50th anniversary of one of Nike’s greatest sneakers, the Cortez. An iconic silhouette, the Cortez has evolved from being a technologically advanced running shoe (at the time it was released) to becoming a pop culture icon, finally resting on being an all-time classic. Who is Kihachiro Onitsuka? Onitsuka was a military veteran who eventually decided to venture into the shoe business. He began making footwear for top athletes under the business name "Onitsuka Co." This company started small with just a handful of employees and initially sought to produce basketball shoes. While the Cortez was a staple within the running community, 1976 saw it explode into pop culture. In an episode of Charlie’s Angels, the actress Farah Fawcett can be seen skating in a women’s version of the leather Nike Cortez titled the ‘Señorita Cortez’. Following the release, sales of the women’s sizing of the sneaker grew massively, with the image of Fawcett becoming iconic not only in Nike’s history, but sneaker history as a whole.Takahashi, a Japanese long-distance runner, wore ASICS Marathon SORTIE JAPAN to win a gold medal in the international women's marathon. 2. Stefano Baldini and Muzuki Noguchi, 2004. ASICS grew from a two-person team to one of the world’s most influential sports brands. ASICS was built on the idea of “Anima sana in corpore sano,” a Latin phrase which translates to "a sound mind in a sound body". This philosophy became a legacy that remains an essential part of the brand to this day. This product was worn in various professional sporting events, thus paving the way for Onitsuka to build a global sporting empire. Are ASICS and Onitsuka the same company?

At the time, adidas had released a running spike sneaker called the ‘Azteca Gold’ which featured a very similar shape to the Onitsuka spikes as well as similar overlays on the heel and used a similar name. With this being the case, Bowerman was tasked with finding a new name for the sneaker, this time choosing the name ‘Cortez’. Since its release, the Nike Cortez has seemed to dip out of favour from the mainstream with attention moving to basketball sneakers and Air Max as time passed. Nevertheless, Nike has been able to keep the spirit of its very first silhouette alive, with many still holding it in high regard. Few shoes have created such a seismic shift in the sneaker business. A court later decreed that both Onitsuka and Nike could sell the Cortez model. Nike retained the shoe’s original name, while Tiger dubbed their version the ‘Corsair’.Acting almost as a final jab at adidas, the Cortez name was derived from the Spanish conquistador Hernan Cortes who led an expedition which brought the fall of the Aztec Empire in the 1500s. While 2018 saw two further colourways of the Lamar x Cortez amongst a myriad of additional colourways and collaborations, including Stranger Things in 2019, the sneaker once again began to wain in mainstream popularity. During the ‘80s, the Nike Cortez continued to be a huge success in pop culture, particularly finding its footing within the music industry. In the mid-'70s - early ‘80s Sir Elton John worked closely with Nike to create his own Cortez sneaker which featured the midsole design of the 1979 Nike Roadrunner.

The following year, in 1967, Bowerman and Onitsuka wanted to change the name of their heavily praised release, and with the Mexico Olympics arriving in 1968, Bowerman decided to change the name to ‘TG-Mexcio’, which promoted some of the adverts for the sneaker to include the word ‘Mexico’ on the lateral side of the shoe. By 1975, three variants of the Nike Cortez were in production including the now-classic leather version as well as a suede variant and nylon finish - the nylon weighing in at around 0.34 KG, ‘the worst lightest running shoe’ as proclaimed by Nike at the time. During this time period, ASICS created innovative products used by professional athletes around the world. ASICS champions in the 2000’s 1. Naoko Takahashi, 2000.
