The Adidas Ultraboost 21 is a neutral running shoe and perfect for your daily runs. The maximum cushioning gives you a lot of comfort and is at its best when used for calm exercises. The Ultraboost 21 has an elastic sock-like upper made of Primeknit. The midsole is made of BOOST material and is very comfortable. It is all about energy-return. Every step you take gives you energy in return. A plate of the Torsion-System is under the sole, which gives the Ultraboost 21 more structure, control and stability.
