Before proceeding with the Adidas Ultra Boost Uncaged Review a brief introduction to Adidas technology is appropriate.

What is Adidas Technology?

Adidas Boost is the most innovative cushioning technology created by NASA. The technology uses a material referred to as thermoplastic polyurethane (TPU) providing comfort that compresses under pressure for better shock absorption. The foot instantly bounces back to its original form.

BOOST foam is made up of lots of little pebbles of TPU and is believed to offer the highest energy return of any running shoe on the market. This allows you to use much less energy, allowing you to run further and faster.

Adidas energy boost redefined cushioning when it launched in 2013 as the primary Adidas shoe to introduce BOOST technology. The light-weight, neutral running shoe introduces a mixture of cushion and quick responsiveness for many who need each run to really feel quick, without sacrificing cushion level.

Design – Material

The upper body of the shoe is fully covered with pure Primeknit. It makes the shoe super soft, flexible but firm enough while giving a great feeling of comfort to the runner. Offers outstanding flexibility and breathability. Primeknit is amazingly soft but not too soft to the point you can feel uncomfortable.

Compared to the classic UltraBoost model there are two major changes, the ankle collar and the missing cage.

  • The ankle collar is now elastic and can be stretched to fit comfortably all sizes. This way the shoe resembles even more with an actual shock.
  • The cage is missing. Adidas removed the TPU stripes from outside, but they add Nylon backing inside of the shoe and put glue overlays around the laceholes to prevent Primeknit from ripping off.

If you are looking for extra comfort then the Ultra Boost Uncaged is the best choice you could possibly get. After wearing these on a daily basis for casual wear, you will not be able to put any other shoes.

Cushion

The BOOST cushioning system is state of the art. The light foam in the midsole provides a bouncy feel in the foot strike while feels supportive and cushioning. During the run the shoe feels very comfortable and responsive. Each and every year BOOST is evolving.

Cushioning is identical to the original Ultra Boost.

Traction

The traction level provided by adidas UltraBoost Uncaged is more than sufficient. Continental rubber is used for the outsole. It is a company that specializes in making tires, so the outsole is very durable and has a great grip.

Depending on indoor or outdoor training the traction varies. In case of an indoor run, traction pattern performs perfectly on an inside track and the grip is exceptionally responsive. However, for an outside run, the traction depends on the terrain and the weather conditions. In wet conditions the grip loosens and the runner is more exposed to potential slippage.

Fit

The Uncaged Ultra Boost provides Primeknit comfort. Initially, when you wear it for the first time the ankle collar can feel a bit tough on the ankle. However, after wearing them for a few days the foot gets used to it and the knitted collar wraps your foot very nicely.

This model is slightly larger than the caged Ultra Boost. That’s because of the minimal heel design allowing the foot to sit rearwards in comparison with the caged structured heel. When the foot sits backward, it creates additional room in the front of the toes.

The fact that the upper part of the shoe is made from Primeknit mesh allows the shoe to adapt to every type of feet. However, the Uncaged version doesn’t have any support features besides the external heel counter and Torsion system. If you have no prior experience in this kind of shoes, I suggest that you try them on before deciding on the size.

The upper part provides, one-to-one fit and does not constrain the natural movement of the feet. It’s like wearing socks.

Support

The Ultra Boost Uncaged lacks support compared to core performance running shoes. The absence of an external midfoot structure and the reduced upper supportive layers forces the shoe to fall short of performance running standards.

This model provides minimal support. The external heel counter and Torsion system did the job well delivering a secure feel in the heel area. However, by removing the external midfoot cage, the foot is not protected from changing directions or even rolling over the midsole.

This means if you are a serious runner this model is not the best option. Still, for casual wearing, this is ideal – nice to feel freedom in the forefoot area.

Conclusion

The Ultra Boost Uncaged is a great shoe, similar to the original Ultra Boost. The removal of the external midfoot cage improves the flexibility and comfort of the shoe while reducing support level. It is very stylish, offering excellent cushioning and is packed with boost foam. The Continental rubber sole delivers great traction and durability.

It is an ideal shoe for amateur runners and casual wearing.
