Based on the reviews of more than 4000 professional runners, Adidas came in 2019 with its latest version of Boost midsole and innovated it by adding 20 % of material to the heel part of the midsole construction. And what has it improved? I can definitely say that Adidas UltraBoost 19 truly became more responsive than my previous Adidas Edge Lux or On Cloud X running shoes that I had run in just before.
I started using the Adidas UltraBoost 19 a few months ago at in beginning of this autumn 2019. I got them as a present after having my previous model of On Cloud X worn out hardly. Both shoes I bought for their special look and good running attributes. Especially the midsole. And I can say that while On Cloud X was more the matter of fashion, style and originality, Adidas UltraBoost 19 won the battle on the other side, with its midsole cushioning. Just from the look, you will easily notice that it has some serious high heel reinforcement, plastic stripes on the sides and high layer of cushioning (10 mm heel drop). The first two improvements keep the heel in the right, straight position so that Adidas UltraBoost 19 helps a runner against any excessive pronation. I immediately noticed the strong heel counter when taking the shoes for the first time on. Simply, it doesn´t let your arches to roll inward. So specifically speaking, that was far better than those On Cloud X which are lower in the heel and so less protective and less helping pronators with their flat feet. The story of Adidas UltraBoost 19 is definitely different. It is a shoe that very efficiently diminishes the feet pain if you have dropped arches. Moreover, as I said, the shoe is strongly cushioned with UltraBoost midsole layer. I don’t know whether it is for the material that the company shows off with or because of the huge thickness of the midsole, but the simple truth is that the material is of high quality. I have been running in these shoes for the last three months and the midsole still remains freshly firm, strong, not getting soft so that the support of Adidas UltraBoost still remains pretty much the same.
In the result, I really like these shoes and I can barely find something negative about them. There has been no need to break in these shoes because from the first run, they felt comfortable, wide enough in the toe box and thus for anyone having the above mentioned pronations problems, this is the real deal. It fits exactly true to size and and in case you are a long-distance runner having wide feet you will definitely appreciate them.
