  • 86 / 100 | Hes Kicks

    I think they're really comfortable and I like the overall look of these.

  • 88 / 100 | Mr. Stoltz

    The new Ultra Boost Uncaged is simply epic. It is, by far, one of the most comfortable shoes I've ever worn, and even better than the previous Ultra Boost.

  • 91 / 100 | WearTesters

    If you don't want to spend $180 on a "fashion runner," then don't, but don't let the Ultra Boost Uncaged fool you-it performs as well or better than ANY other shoe out there, provided you acknowledge the support factor.

  • 86 / 100 | Bryan Hinkle

    If you're a neutral runner with a very strong gait, very neutral run, very easy stride, definitely check this out as a performance shoe.

Updates to Adidas Ultra Boost Uncaged

  • Endless energy is given to the runner when they put on the Adidas Ultra Boost Uncaged. This running shoe delivers responsive cushioning, which is also lightweight and flexible. A boost of energy makes each step feel enabled, and it’s largely thanks to the springy boost™ full-length foam. The upper coverage looks and feels like a sock, thus permitting freedom of movement.
  • The outsole unit of this running shoe makes use of a rubber material that is elastic. It adapts to how the foot comes in contact with the ground, thus keeping it balanced and well-supported. It also works with the mid-sole in order to make the heel-to-toe transitions as smooth as possible for the wearer. The outsole isn’t stiff, as well.
  • The platform of the Adidas Ultra Boost Uncaged uses the high quality boost™ technology. Its springy nature energizes each step, allowing runners to land comfortably on the ground and then lift off with more oomph. It’s made from durable materials, so it won’t easily break down.
  • The upper unit features the Primeknit system, an engineered material that looks and feels like a woven fabric. It moves along with the foot, expanding as it lands on the ground and flexing as it rears for the toe-off. The SOCKFIT construction reduces irritation, especially when wearing the Adidas Ultra Boost Uncaged without actual socks.

Adidas Ultra Boost Uncaged size and fit

The Adidas Ultra Boost Uncaged uses standard measurements for its length. Men and women are able to get the correct size when selecting this model. The available width for both genders is medium, so those with medium sized feet are able to acclimate well to it when wearing it. Its semi-curved shape follows the natural curve of the human foot.


The STRETCHWEB outsole shields the rest of the sole unit from wear and tear. Its elastic nature adapts to the surface, expanding itself to balance out each step the runner takes. It even works alongside the mid-sole to return energy to the runner. This rubber material also delivers reliable surface traction, which is essential for every running session.


The boost™ mid-sole is made up of thousands of TPU pellets that have been molded together. This material is lightweight and responsive. Its springy nature energizes the runner, making each landing well-cushioned and each liftoff more enabled.

Mid-foot integrity is given by the TORSION® SYSTEM. It also allows the rear and the front sections of the foot to move independently, thus causing each step to become smoother and more efficient.


The Primeknit is a material that feels like cloth. It follows the shape and motion of the foot, essentially giving way for natural movement. It’s lightweight and flexible, too.

The SOCKFIT lets the runner feel a snug and secure fit. It works like a sock, wrapping the foot comfortably without causing skin irritation.

The FITFRAME 3D-Molded TPU is placed in the heel area. It stabilizes the heel and keeps it in place, so it basically prevents wobbling of the foot, as well as accidental shoe removals.
