An icon returns. The Ultraboost 5 have arrived to boost your energy in every run. Run like never before, with innovative design for greater shock absorption, more comfort, and less weight.

LIGHTBOOST is Adidas' Boost shock absorption system that offers the highest energy return with every move.

Light Boost is the new generation of adidas Boost: 30% lighter, for even greater energy return.

The super anatomical PRIMEKNIT upper ensures a perfect fit, while the external heel clip with improved design offers support where it's needed most.

PRIMEKNIT provides adaptability and improved fit in key zones, maximizing breathability where possible, so the foot stays cool with every step.

"The Ultraboost is a true icon of running and this is our best one yet," says Simon Lockett, Footwear Product Marketing Category Director at adidas.

"82% of people who tried it say they prefer its energy return over their own shoes and 70% say they had more fun while running in it. This has always been the superpower of the Ultraboost, especially now that it has returned with more Boost and lighter weight than ever."

For the first time, Adidas introduced two versions of its popular series, the Ultraboost 5 and the Ultraboost 5X.

Both models feature a Primeknit upper, Light Boost sole, Torsion System, pre-molded heel clip, and Continental outsole.

The Ultraboost 5X, however, weighs 17 grams less (it does not have the cage on the upper part where the laces tie) and is an ideal choice for runners who prefer a lighter shoe.
