Adidas - Ultraboost 21 Women's Running Shoes - Black - UK 4.5

The adidas Ultraboost 21 for women are neutral, all-round running shoes. The Ultraboost is an ideal shoe for your daily runs in urban or more rural areas. These 21st version of the model boast a Primeblue upper which is made for 90% out of recycled materials. A core element of Primeblue is Parley Ocean Plastic. With their Parley Ocean Plastic campaign adidas really works on creating a sustainable means of production. The High Performance upper comfortable encloses the feet without becoming too rigid. The upper is one single piece of material and doesn't have any seams. Thanks to their seamlessness the shoes offer a very comfortable fit. The striking thick Boost midsole provides more responsive cushioning when landing over the heel; the energy you put into your stride is returned to you during toe off. The Boost cushioning material withstands changes in temperature like no other midsole material; so, whether you're running in warm or cold condition, you'll always enjoy maximum cushioning. Added to the forefoot of the shoe is the Linear Energy Push system. This new part of the Ultraboost model increases the stiffness in the fore and midfoot of the shoe, and also ensures an even higher energy return. The Continental Rubber outsole, also featuring StretchWeb technology, is made of rubber from the car tyre giant Continental. This rubber is very durable and provides a lot of grip and traction in wet as well as dry conditions. By using Primeblue material and Continental rubber adidas reduces the impact their production process has on the environment. Thanks to this you can run comfortable and carefree, while at the same time contributing to a better and more sustainable world.
