As every year, Adidas launches the running shoes from the Ultraboost series, when again this time, the new model - Ultraboost 5 focuses on improvements in the energy return of the shoe.
The energy return effect in the shoe absorbs the impact of each step and converts it into momentum that helps conserve energy and improve during running. This is one of the popular topics in the running world, which deals with how much energy return improves running too much?
One of the explanations in favor of technology, that in the end you have to invest energy in running, in order to get it back, therefore you still have to be a good athlete.
Adidas says that the Ultraboost 5 this year received a 2% greater energy return than the previous model - Ultraboost Light. Adidas uses a redesigned Light Boost insole with 9mm more foam under the heel and forefoot, allowing for weight reduction and higher cushioning. The insole filled with Boost offers a higher response and it returns to its original shape immediately when the foot hits the ground, which ultimately allows you to run for greater distances, while investing the same amount of energy.

The shoe itself offers a more comfortable and airy feeling, thanks to the new upper part called - Primeknit. This part is produced with knitting technology that wraps the foot in a sock-like spring. It is better adapted to the shape of the foot, so that more air reaches the foot. Also, due to the configuration of the Primeknit, the shoe does not have a tongue that could move while running.
The rubber sole of the shoes comes from the Continental company designed to provide grip on different types of surface, they have a drop of 10 mm and the weight of the shoe is 248 grams in size 38 and 292 grams in size 42.
