Embrace running again in a shoe that won't feel like the old clunky kicks you had back in the day. Short shorts, tube socks, and uncomfortable trainers are out, and synthetics, smart fuel, and the Adidas Men's Ultraboost Running Shoes are in. Though Adidas has integrated its proprietary Boost foam into many of its shoes, the Ultra Boost features 100% Boost cushioning on a lightweight, flexible platform. In addition to Boost foam, the shoes also feature Adidas' Torsion System and FitCounter support. Torsion System ensures stability around your midfoot as you transition from heel to toe, while FitCounter wraps reassuringly around your heel to allow your Achilles to flex and extend naturally. To beef up traction and durability, Adidas adds Continental Rubber and StretchWeb rubber to the outsole, further increasing the miles this long-wearing shoe will give you.

I normally take a 2E width in running shoes, so after reading reviews about the Ultra Boost, I figured it would be a no-go for me. After trying one on in a local Adidas store, I was pleasantly surprised at how accommodating the PrimeKnit actually was to my slightly wide forefoot. I normally take a 10.5 2E in running shoes (unless they run a little wide), and the Ultra Boost fit great, 10.5 D is perfect. The width accommodation has only gotten better as the days go by and the PrimeKnit has conformed to my foot a little more. Lots of toe wiggle room available, but only after I fixed one thing...My only real complaint that hasn't gotten better is that the toebox is very shallow.

Meaning, there is a good chance you might have a little pressure on the top of your big toe if your toes aren't skinny/flat, and you'll see that Ultra Boost toe bump all the time. I replaced the stock Ultra Boost insole with a old (half as thin) insole from an old pair of New Balance Zante, and that gave me a little extra room all around, including a little extra much needed depth in the toebox. Made a great shoe even better. The stock insole also has no side lip area for the arch like most running shoe insoles do. I'm not talking about true arch support, but just a soft area to protect the arch from the side of the shoe. The Zante insole fixes this too, but adding that extra lip for more complete foot comfort.I'm using this mainly as an everyday work/casual shoe due to the comfort, but I may pick up a 2nd pair to dedicate to running. Pricey, but it really does feel fantastic on my feet. I've been having a hard time finding a good everyday sneaker that fits well and is comfortable, and I've found that in the Adidas Ultra Boost.

I use the Ultraboost 3.0 for casual walking and light running. The shoe runs long and the upper is made up of a really stretchy prime knit. Because of this, it is best to go a whole size down from your true Nike Size. Even with going a whole size down I still have a tad bit of room in between my toes and the front of the shoe, which is how I like it. I usually wear a size 10 in my Nike shoes and other brands. I wear a 9.5 in the Ultra boost 2.0 and and a 9 in the Ultra boost 3.0. I also use Insite Insole orthotics on top of the stock insole for arch support and extra stepping comfort. I would ultimately recommend trying these shoes in stores first as everyone's foot is different. I have a normal foot to a slightly wide foot.

Definitely a unique fitting shoe. Could not get a good heel lockdown for running, regardless of how I laced it. The plastic cage has a tendency to dig in to the side of your foot if you lace too hard anyway. These were not really practical for real running, but I tried to give them a shot as everyday shoes. The toe box is extremely shallow. If your big toes are anything but very flat and small you'll get a visible bump where your big toes are. The pressure from the knit fabric on the edge of my big toe drove me nuts and caused some discomfort. The shoe would only work if I removed the sock liner, but then the underfoot comfort was compromised. I tried different insoles, but all just make the toe box too shallow again. I wanted these to work for me, I even tried to ... MoreDefinitely a unique fitting shoe. Could not get a good heel lockdown for running, regardless of how I laced it.

Just be aware your foot volume and characteristics will determine whether or not this shoe works for you as a lifestyle shoe. Still not convinced this could be a serious full time running shoe in any scenario.

I would like to note that this pair of shoe has only been used for urban and indoor use. From that perspective I would like to say that these are phenomenal shoes for keeping my feet supported and comfortable throughout the day. They're also incredibly lightweight and have a sock-like feel adding to that comfortable experience. I'm always on the move with these and so far I deeply value the purchase. I have no doubt that these would also do well for their intended purpose which is running, however I would recommend going for the other runner focused "boost" shoes from Adidas as this pair of Ultraboost is more geared towards everyday lifestyle use. These may run small if you don’t like the tight sock-like feel of the shoe so I would reccomend going up half a size.
UNBELIEVABLE!!! I normally have a grave yard of running shoes... new balance... mizunos... and last was Brooke's. I thought I had met my soulmate with Brooke's running shoe. But this one caught my eye and the design looked like it just might fit my needs. So I went ahead and splurged on a brand that I thought I would never invest in. All I can say is this, and I NEVER DO REVIEWS, I have never had a running show with this performance and glide. I am getting back into running after a hard surgery 2 years ago and this shoe makes me feel like I have never stopped running. I have no shin splints, my gate is graceful with no rebound (its like running on a cloud-no other way to explain it) and it makes it hard for me to stop (Kinda feel like Forrest Gump-but still).

The only thing that has hindered my running is my endurance with breathing. That is fixable naturally. My legs and knees and feet.... the shoes work perfectly to protect me from injury, especially since I am working on my gait and endurance again! Perfect engineering in this shoe. Totally in love!
Love this shoe. They're probably the most comfortable shoes I've ever worn. "Walking on clouds" was a common review I read about them and I have to agree with that sentiment. In terms of sizing, I had to buy them without trying them first due to proximity of shoe stores. I normally wear size 9's but I went up a half size and that was a good choice. I think it will ultimately boil down to whether or not you prefer a tighter fit or a slightly looser one. Either way they should work because the flyknit technology will allow for stretching over your foot but I like them looser for comfort sake.
Best shoes I've ever owned. I've used Mizuno Wave Rider and different versions of Asics Gel Cumulus in the last 7 years. I didn't even have to break into it, just felt awesome from day one. It realy fits like a glove - I think I could cut off the "cage" and get away with it. The sole is awesome - super light but great cushioning ! The stretch fabric upper is outstanding. For those with wide feet, this is brilliant - it just expands just like socks and it is super breathable.This cost me twice of what my other running shoes cost on average - but I felt like it was totally worth the extra $$One problem though - at the inner side of one shoe, the stitching came out afetr just 100 miles.

I think I just got a bad piece - I know other runners in my group who donot have such problems.Another minor problem - the lace tends to come off frequently; I've not faced this with Asics Gel Cumulus last several yearsI would give this a 5-star rating if not for the damage that came too early. I've heard others say this would easily last close to 1000 miles !
I really wanted to love these, but should have listened to the reviews that stated they don't provide enough stability. I have run numerous marathons and always worn Asics, but noticed the quality of Asics is no longer what it once was. After much debate, decided to give the boost a try. When I put them on they are super soft and do fit according to my correct shoe size. When I attempted to run on the treadmill, they felt loose and have absolutely no stability, my feet were slipping all around the shoes. I promptly took them off and loaded them back in the free return box and sent them on their way. Not for me. I have had plantar fasciitis and hip issues, so require more support and stability. Very grateful Road Runner has free returns. I'll purchase from them again ... MoreI really wanted to love these, but should have listened to the reviews that stated they don't provide enough stability.

If you just want soft cushiony walking shoes or even workout shoes, you may like them.
Pass on the Adidas Ultra Boost...After reading all the glowing reviews on this shoe, I felt it necessary to relatemy very different experience.First off, let me say that Adidas in my past experience were absolutely wonderful,had used them for years.This version, Ultra Boost, however, was just plain 'weird.'The fit was OFF in both length and width for sure,but beyond that they felt like you were running in house slippers.I tried to give them the benefit of the doubt by alternating themwith several other vendor's shoes. But by the time I had solidifiedand confirmed my decision with testing, it was too late toreturn them. I would definitely NOT get them again.
After 3 months of running with these shoes, I regret not returning them while I still had the chance. Because I have wide feet, the cage on the shoe is very uncomfortable; it feels like my arches are being squeezed no matter how loose I lace my shoes. Adidas makes this shoe in only one width, so I would not recommend this shoe for anyone with wide feet.Aside from the uncomfortably, I really like the color and the design. The cushion is very good, but not as comfortable as the Brooks Ghost line, which is what I had before trying these shoes. The problem with Brooks, however, is that their shoes are pretty ugly, but Adidas makes a pretty snazzy looking shoe.I'd recommend this shoe to anyone who prefers the Adidas brand and does not have any foot problems, like ... MoreAfter 3 months of running with these shoes, I regret not returning them while I still had the chance.
