The Adidas company has released a state of the art running shoe that is first of its kind because of the added technology within the shoe. This energy focused sneaker is called the Ultra Boost. “The Ultra Boost features the first combination of the improved Boost technology with a four-way-stretch Primeknit upper. A completely new type of outsole merges different technologies into one shoe that Adidas claims allows for full natural movement of the foot while providing the most energy return of any cushioning system on the running market.” According to Sports Illustrated, this sneaker allows runners to have maximum energy and cushion in one. As an avid runner myself, cushioning is extremely important to the foot because the harder you run on any type of surface will create tension within your bones and muscles. Cushioning your feet correctly will help stop injury in your feet and legs. This technolgy starts with a special type of foam called EVA foam which absorbs more energy than any other foam on the market. Flexibility is also a key component on why this sneaker is so technologically advanced. The Adidas team used a camera inside the shoe during research to see how exactly a foot moves inside and where the constraints were. Adidas has truly stepped up their game recently in the sportswear market and I think this Ultra Boost technology will definately give Nike a run for their money.
