adidas Ultraboost Winter.RDY Running Shoes
You give it your all year-round, and you need running shoes that can keep up with your training regimen. These adidas shoes have a knit upper that gets a winter finish with added water-repellency. The rubber outsole is engineered for traction on rough ground. Fly through the streets of your city, no matter the season.
New Primeknit 360 Upper
A new and updated Primeknit 360 upper will encase each foot in breathable comfort. Feeling like a second skin, its seamless construction surrounds the foot in a fused yarn that combines pure comfort with lightweight performance. Designed with motion in mind, the Primeknit 360 adapts to the changing shape of your foot through the gait cycle, the breathable, sock-like design is engineered to provide enhanced support and increase comfort to areas of the foot that require it most. The Winter.RDY aspect of the Ultraboost provides you with a water repellent upper protecting you from light rain. Additionally, a speed lacing feature with a toggle has been added allowing you to lace up quickly instead of having to stand around in the cold.
The Ultra Boost Winter.RDY has kept the supportive cage that many runners loved in its predecessor, securing the midfoot and reducing in-shoe slippage for a smooth, distraction-free ride. Lastly, the upper boasts a 3D heel frame, another update, which offers the perfect mix of adaptability and support. Built from a combination of flexible and supportive materials, the stripped back design cradles the heel on impact to inject more confidence into your run. this new construction allows optimal movement of the Achilles and surrounding soft tissue while still providing support.
New Optimised 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 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.
