adidas, started a new era in the world of performance footwear with its Boost soles that have the ability to convert energy. The adidas Boost shoes, which were launched in 2013, were revolutionary with their unique features. The soft and flexible adidas Boost was designed by the adidas Innovation Team (AIT) and chemists from the German chemical company BASF. In addition to the flexibility and cushioning features that provided perfect support during movement, the sole had the ability to convert energy. The Boost technology produced for the running series became an icon in the running world and was also used in other sports shoe models and sneakers designed for street fashion. Boost technology has continued to develop since its launch and continues to be the leader of performance shoes.

What is Boost Technology?

Until 2013, the material that provided performance support in running shoes was EVA foam. EVA foam is still used in many running shoes. Despite its soft structure, EVA is an extremely durable material. It is comfortable due to its lightness, and offers runners comfortable cushioning and flexibility. However, the cushioning and responsiveness properties cannot be increased at the same rate. When more cushioning is desired, the softness of the foam increases and the responsiveness time increases. When a faster response time is desired, the sole becomes harder and the cushioning feature is limited. Boost is designed to eliminate this dilemma.

The features missing in EVA foam are present in Boost technology. Boost is produced with Thermoplastic Polyurethane, a type of elastomer. This material offers unique cushioning and flexibility to the sole, while not reducing the response time of the sole. In addition, the sole is still lightweight, and thanks to its increased durability, it lasts longer. Shoes designed with Boost technology are revolutionary, but the flexible, durable and load-bearing material that makes up the technology is not new. This material has previously been used in bicycle helmets and car seats. Its adaptation to the sole of a shoe is new.

The Boost sole, which is obtained by creating closed cells around the air pockets of expanded TPU particles, gives the shoe five different features.

Five Features of adidas Boost

1. The adidas Boost shoe captures the athlete's kinetic energy, traps it inside the sole and returns it to the athlete. This ingenious energy-recycling invention has made Boost an icon in the world of performance footwear.
2. The sole created with closed sacs formed around the air sacs offers perfect cushioning. This feature provides the athlete with an extremely comfortable experience.
3. The durable structure of the sole is not only resistant to abrasion but also to weather conditions. Boost soles can be used in all seasons and in all climates. They are resistant to water, snow and heat.
4. Boost supports the foot at every speed with its flexible structure.
5. In addition to all its features, it has a durable and long-lasting structure. It does not wear out easily and does not lose its strength over long distances.

The Development of Boost

Adidas continues to develop the Boost technology that it introduced to the market in 2013. The shoes are renewed at certain intervals with different features since the year they are released. The Ultraboost series of models, which we see a more advanced version of every year, has increasing popularity.

Designed for performance running and competition, the adidas AdiZero Boost is the model used by athletes who break world records. The thick soles of the shoe, which feature comments from famous adidas athletes in its design, provide extra cushioning.

Adidas's Boost sole is 100 grams lighter than the Sub2 Boost model, which maintains its unique cushioning feature. Developed for competition, these shoes are the choice of athletes looking for a lighter option.

Ultraboost is the new revolution that took place within Boost in 2015. This time, the adidas Innovation Team designed the Ultraboost soles inspired by a space technology. Ultraboost is an anatomical adaptation of NASA's ARAMIS technology. The technology, which allows the athlete's foot movements to be examined in detail during running, has helped create the perfect sole structure. Ultraboost is a constantly developing model and has continued to be popular as both a performance shoe and a street fashion icon since its launch. This popularity is due to the superior features of the soles and the fact that it was launched by Kanye West. The model also has a special collection for the famous TV series Game of Thrones.

Ultraboost 21 is one of the most popular models of the adidas Ultraboost series. The LEP system is used on the outsole of the model with a 6% increased Boost sole. LEP (Linear Energy Push) is a system that provides a faster response. It increases the response speed by increasing the toe and midsole balance of the shoe.

Ultraboost 22 shoes The upper used in the models is reinforced PrimeKnit. It wraps the foot and supports it comfortably. 50% of the upper's fabric part is made of Primeblue yarn, which is produced from 92% recycled material. The sustainable adidas Ultraboost 22 is a popular model preferred in both performance running and street fashion. The more advanced version of the model, designed with a Gore-Tex upper adidas  Ultraboost 22  Gore-Tex Shoes running shoesis.

The sole structure is compatible with all weather conditions, making it ideal for the sole of an outdoor shoe. For this reason, adidas, hiking and outdoor shoes Terrex used Ultraboost technology in the soles of its models.
