Material and Design

The Ultraboost 4.0 shoes come with a sleek, smooth and minimalist design. With the breathable knit materials in the upper, the shoes give a modern look. Moreover, the adidas stripes are present on the sides of the shoes while the logo is present on the tongue and heel. However, in color options, the shoes offer a variety of colors from black to white to more vibrant shades such as blue and red.

On the other hand with the stretchweb rubber compound outsole, the Ultraboost 5 offers a natural and flexible feel as well as grip. However, the outsole is lightweight compared to the Ultraboost 4 outsole. 

With TPU full-length boosted midsole and pellets, the Ultraboost 4 shoes allow energy return and responsiveness at each step. Moreover, the boosted technology minimizes the risk of fatigue during long runs. While Ultraboost 5 also has the same boost compound with some updates which make these shoes 20% more responsive. Also, these shoes use a torsion system in the midsole. 


The Ultraboost 4 has incorporated boost technology that ensures exceptional energy return at each step as well as this technology absorbs stress and releases it during toe off which then offers a more responsive ride. 

However, Ultraboost 5 also uses the same technology with updates for a more explosive and energized experience so it is famous among performance-oriented runners. 

With the addition of supportive and stable features, the shoes ensure high performance on all surfaces during running. 


Ultraboost 4 and 5 are designed as durable running shoes because of the incorporated sturdy continental rubber outsole. So you can run on long mules without causing any damage to your shoes. 

However, the rubber outsole is optimized in new version 5 so it offers abrasion resistance and allow the outsole design to flex as the foot move which further increases its lifespan and keep the shoes durable for regular running.
