Upper
You’ll probably notice the upper first when looking at the Adidas Ultra Boost Uncaged. It’s an odd sock-like upper that you can slip into with ease. Putting on the Boost Uncaged feels like slipping on a pair of socks. There’s no firm, snug feeling in the upper. It’s made up of Primeknit material like the previous Boost iteration but any rigid parts have been stripped on this model. There a much more flexible feeling to the upper. This makes the shoe perfect for hot weather running since the sock-like upper is nice and breathable. If you prefer a more structured fit, you might not enjoy the Boost Uncaged. Some runners might also find it annoying to have to physically pull the shoes on and off. Because of the sock-like cuff in the upper, you can’t just slip your foot into the shoe like you might be used to.
Midsole
The midsole of the Adidas Ultra Boost Uncaged is made up of TPU Boost foam. This foam is light and its main job is to cushion each footfall. There is a lot of nice, bouncy foam in the Boost Uncaged. You’ll feel like you’re running on a pillowy cloud. The Boost cushioning is unrivaled in its ability to support and cushion. If you’re interested in being comfortable on your run, a shoe with Boost cushioning is a great choice. The Adidas Boost foam is super responsive and doesn’t lose its cushion after daily use.
Outsole
The outsole of the Adidas Ultra Boost Uncaged is made of Stretchweb. This material aims to lower the amount of impact a runner’s body will feel during a run. The shoe also contains a Torsion System which increases the stability of the shoe, making it a good option for overpronators. The Stretchweb rubber outsole also helps with traction and increases the shoe’s durability.
Breathability
The sock-like upper on the Adidas Ultra Boost Uncaged means that the shoe is super breathable. The Boost Uncaged is the perfect option for runs in hot weather climates or on hot steamy days elsewhere. Like a good pair of socks, they wick moisture quite well and the thin upper material is durable but allows a runner’s foot to breathe. You won’t feel uncomfortably hot in this shoe and that’s a good thing since you’ll likely want to keep them on all the time.
Comfort
The Adidas Ultra Boost Uncaged are super comfortable. The Boost Uncaged feels like slipping on a comfy cushioned pair of super stylish socks. The Boost cushioning is like no other cushioning out there and you’ll have a bouncy, responsive ride every time. Although the Boost Uncaged upper is sock-like, you might want to keep your socks on when wearing this shoe. Some runners mentioned that when worn sockless, they had issues with inner seams causing unwanted friction.
Style
These are a seriously stylish shoe. In fact, they’re a welcome combination of running and fashion shoe. There are some fancy touches on the Adidas Ultra Boost Uncaged that you may not have noticed. The heel of the shoe actually features a bit of gold lettering, just to let you know that this is a fancy shoe. The higher price tag on this shoe comes from the fact that it’s so stylish. You can get away with wearing this shoe casually.
Durability
The Adidas Ultra Boost Uncaged features a different design in its outsole than the previous version. The lugs on the bottom of the shoe are now flattened in this version to increase the shoe’s durability. These shoes won’t last you forever, but they’ll last a few hundred miles for sure. The best part? The Boost foam cushioning doesn’t quit. It should feel bouncy and responsive for quite a while.
Protection
The sock-like upper on the Adidas Ultra Boost Uncaged means great breathability and more freedom of movement for the foot. But a sock-like upper also means a thinner material that leaves your foot a little bit more exposed. Either way, the Boost Uncaged offers great protection from successive pavement pounding. The Boost foam goes the entire length of the shoe and it definitely does its job in making things comfortable and absorbing shock.
Responsiveness
The Adidas Ultra Boost Uncaged is a super responsive shoe thanks to the evenly placed Boost foam cushioning. Every step offers bouncy feedback for the wearer. If you’re not already convinced of Boost foam’s excellence, try it. You’ll get a nice springy ride out of the Boost Uncaged. And to top it off, it’s a ride that’s also nicely cushioned.
Support
With the removal of the plastic cage in the Adidas Ultra Boost Uncaged, the shoe is true to its name. The result of a flexible sock-like upper that allows for freedom of movement. Unfortunately, this reduces the amount of support in the upper. Some runners might not like the amount of flexibility provided with the removal of the cage. It’s still a snug fit, but there’s definitely more movement. The heel cup does ensure that the heel stays in place during a run. You’ll also get support thanks to the generous infusion of Boost foam throughout the shoe’s midsole.
Terrain
These are meant for the road. It’s clear that the Adidas Ultra Boost Uncaged is not a trail shoe by any means. They scream fashion and although the outsole is made of Continental brand rubber, they’re just not meant to be taken off road. Still, go ahead and take them out in the city. You’ll look good and feel comfortable in the Boost Uncaged.
Price
These babies are definitely high in price. You’re paying for fashion with the Adidas Ultra Boost Uncaged. There’s little more to it than that. They’re a well-made shoe with ample amount of cushioning, but they’re also more expensive than a shoe that offers a similar amount of cushioning and are good quality. You’ll be paying extra bucks because these shoes can be worn casually as well. Similar to the Nike Free, you’ll definitely see non-runners snatching up a pair of these for everyday walking around.
Drop
The heel to toe drop in the Adidas Ultra Boost Uncaged is 10mm which is unchanged from its previous iteration. The full-length Boost foam makes the shoe feel quite level, regardless. You’ll also notice that the bouncy cushioning makes for a super responsive ride even though these are not so-called “natural” running shoes.
Stability
There’s some stability in the Adidas Ultra Boost Uncaged, but it’s really all in the arch. The shoe is so flexible and offers such freedom of movement, so it doesn’t really do much in terms of stability. Runners who prefer to be held in when running will feel a bit floppy in the Boost Uncaged. Still, the Boost foam that’s found throughout the midsole offers a steady base for runners. If you’re a severe overpronator, stay away from the Ultra Boost. You’ll want more substantial stability than this.
Flexibility
The full sock-like upper on the Adidas Ultra Boost Uncaged offers more flexibility in the upper than ever. However, the full-length Boost foam does make for a fairly rigid midsole, so the flexibility in the rest of the shoe doesn’t quite match up. The foam is so nice and cushioned that you might just forget about the fact that it’s also a bit rigid. You’ll still get a responsive ride from the shoe and the “Uncaged” upper will be a welcome change in the eyes of many runners.
Traction
The Adidas Ultra Boost Uncaged outsoles are made of Continental brand rubber. The company makes tires so you know that you’re getting an outsole that does well with grip. The new flattened lugs on the outsole improve traction and durability as well. There’s still concern voiced from some wearers that the shoe doesn’t do so well in wet conditions, though. This is a problem that carries over from the previous Boost version. Definitely, watch out when running in the rain if you’re sporting a pair of Boost Uncaged shoes.
Bottom Line
The Adidas Ultra Boost Uncaged is the perfect option if you’re looking for a shoe that can carry you from a run to a casual afternoon shopping trip. These shoes are stylish and they offer super cushioning thanks to the full-length Boost foam. The ample foam distribution does offer some support, but these are not a great choice for those who are severe over pronators. If you’re looking for a bit of support, a lot of styles and a comfortable shoe, the Adidas Ultra Boost Uncaged are a good choice. Just make sure you’ve got a room in your budget for a pair of the Boost Uncaged shoes.
