adidas Ultra Boost is a running model of 2015. Designers of the brand, even before a start of selling announced that it will be a revolution in the field of running. Initially people were quite sceptical about new technology, but quickly found out that adidas designers don’t waste their breath! 3.11.2017 is certainly one of the most important dates in the adidas brand calendar. This is the date of the 4th generation of cult Ultra Boost sneakers! As in version 3.0, also here there’s a main change over the previous version is the way of weaving the upper. It’s nothing else but a new weave that sets the zones of the shoe apart. Men's adidas Ultra Boost 4.0 Primeknit shoes are made with the utmost attention to details and materials. The upper itself took the form of a “sock” adhering to the foot - SOCKFIT made of textile material woven in Primeknit® technology, which with low weight is characterized by incredible strength and aeration. In the midfoot area and heel there are cages made of thermoplastic polyurethane (FITCOUNTER) ensuring proper stabilization of the foot. A label of synthetic material, located in the front part of the upper, serves as a reflection. Inside there is a removable insert and a comfortable textile lining. adidas Ultra Boost sneakers have an inside sole made of cushioning boost™ foam, which returns energy with every step, and TORSION® technology – supporting natural movement of feet. STRETCHWEB outsole with non-slip Continental rubber was also equipped with grooves, so that it better absorbs energy of impact in the heel area, and the foot itself may perform a more natural movement.
