adidas Ultra Boost 20 Running Shoes

Meet your new best friend for your fastest, longest runs. The sleek silhouette and responsive comfort of Ultraboost show up ready for race day and beyond. These Ultraboost 20 Shoes have an upper built with the lightest mesh adidas makes. Internal support locks down the fit when you're powering toward the finish. 3-Stripes inspired by Japanese calligraphy add to the fast feel.

Celarmesh Upper

The upper of the adidas Ultra Boost 20 Running Shoes use Adidas' developed Celermesh technology that will provide you with exceptional lightweight breathability. Air is easily able to enter and exit the shoes constantly, and this process will ensure that you will always feel ventilated no matter how hard your effort is. As you begin to sweat, the moisture is also able to escape out of the shoe, which will keep your feet feeling fresh and dry. The Celermesh construction is extremely lightweight, which will keep the overall weight of the shoe down to a minimum. This will mean that you will feel like you can push yourself further and faster than ever before. The mesh will also hug the feet, which will lock the feet in place for a more efficient stride. Thicker material surrounds the toes and the heel, providing protection from heavy forces and impacts. A traditional lacing system as well as a compression tongue system will provide you with a comfortable and secured fit.

Boost Midsole

adidas again take cushioning and responsiveness to new heights, with their ultra-responsive midsole. As many know now, Boost is constructed from tiny TPU capsules that are moulded together to form a platform that is different to standard, solid foams; absorbing energy and then expelling it back out for a bounce-like effect. This energy return technology reduces the use of superfluous muscle power, diminishing fatigue and enhancing performance; keeping you going for longer. Capturing the energy you put into running and blasting it right back out, the newly optimised Boost midsole brings even more energy return to your ride. What makes this boost arguably better than other midsole compounds is that adidas has made the boost firmer to deliver 20% more responsiveness and cushioning compared to the original Ultra Boost. Boost also manages to maintain its special function and bounce in conditions as low as -20 degrees, making it a reliable, durable and hard to beat midsole. Furthermore, the midsole features a new tuned torsion spring that offers enhanced support on landing and a snappy transition as you surge ahead. The reason is simple: a running shoe shouldn't get in your way; it should propel you forwards. Both of these unique technologies work in tandem to push you ahead of the competition as well as giving you a good basis to break PB's.

StretchWeb Outsole

Manufactured from Continental rubber, the StretchWeb outsole completes the Ultra Boost 20 for superior grip and a smooth transition through the gait cycle. Its web-like structure cooperates with Boost to allow the shoe to stretch, for a flexible and lightweight underfoot feel. The web pattern also means a large surface area which also means better grip. Inspired by tyre technology, continental rubber supplies traction on wet and dry surfaces, giving you no excuse not to get out and run. The outsole is designed to be just as durable as the Boost midsole, leaving you with a resilient, cushioned and grippy running shoe.
