Rated 5 out of 5 by Culmination of all of Adidas' technology While some may scoff at the price. Believe me, they are worth it! This is the best of all Adidas' design tech carefully integrated into a great runner. They are as comfortable as the Pure Boosts, but feel lighter while offering greater stability. The Primeknit construction is seamless and impeccable. The boost midsole is capped with a layer of Continental rubber and is incredibly grippy. DO NOT SLEEP on these. While they are technically brilliant as runners, you can't ignore the style. They look as good as they function. Running sneakers have become a huge part of streetwear, and these are definitely eye-catching. July 16, 2014
Rated 5 out of 5 by Great trainer This is a solid trainer. The sole is a bit stiff out of the box but you'll feel the road as you run. The 4mm heel to toe drop (as I'm told by customer service) is a good minimalist set up for those who prefer a mid foot strike. The fly knit upper is incredible. Zero seams, feels like you have no shoe at all. I'm not sure I would rely on these for marathon distance, but for half-marathon and below training these are a good shoe. The color scheme and design is impeccable. I look forward to my next run in these. July 19, 2014
Rated 5 out of 5 by Boost continues to evolve... I've been lucky enough to own every neutral incarnation of BOOST since the Energy Boost 1. Energy Boost and Glide Boost are both phenomenal trainers, but I have to say I was disappointed in Adios Boost. The upper is ill fitting and overly rigid (it's almost crunchy, and bunches when you tighten the laces).The outsole, while responsive, just felt too flimsy and flexible to be a true racer. Frankly, it doesn't handle the torque that a powerful runner produces en route to toe-off. It just folds right in half. Problem solved with Primeknit. Compared side-by-side with AdiosBoost the outsoles appear identical, maybe they are, but the feel is totally different. The seamless primeknit upper wraps the foot like a glove, giving a feeling of added stability and security that AdiosBoost just doesn't have. My first spin in these was a 16 mile run progressing to marathon pace (about 5:30 mile pace for me). I was hesitant at first, it just felt too light and soft and I figured by mile 12 my feet would be killing me. Wrong, the shoe is light and airy while maintaining responsiveness, stability, and just enough cushion. I even stepped on a couple gnarly rocks with no ill effects. The price may put it out of reach for a lot of people, but I would highly recommend keeping a pair in the back of your closet for those couple big races per year. Phenomenal shoe. July 28, 2014
Rated 5 out of 5 by Wow!!! These shoes are made for physical exertion. Could not believe the comfort and weightlessness of the shoe. Color is dead on sharp for a running shoe. Have had other high end running shoes that don't feel as comfortable as these. Fit is perfect. I went down 1/2 shoe size. Try them you may like them like I do!!!! August 13, 2014
Rated 4 out of 5 by great shoes ... could be better ... I brought these on line and went in to get a different pair since they were a little too loose when i went without socks. + Overall the shoes are well designed. + The fact that the toe box has been "laminated", controls my toes a bit better than another certain competitors' offering which is just fabric. + heel feels great, nice and snug. + Laced up fully, they felt very locked down. + Tongue is very supple/comfortable. No pinching or lumpiness. I'm glad its not a one piece tongue since it makes it easier to get in and out of the shoe. Again see competitor's shoe. + Initially very comfortable to walk around in. Didn't feel like it needed break-in. Haven't had a chance to run in them yet. Will post back in a week after i run in them awhile. + come with second set of laces. + great colors. - Quality was suffering a bit since the fit and symmetry between left and right shoes was off. At this price and with modern technology this was disappointing. BUT I was lucky enough to have an Adidas store nearby that carried the shoe so I could find a pair that was fine. I was told these were in limited release. I hope hey make more and this is the start of a great shoe line. August 8, 2014
Rated 4 out of 5 by Great Running shoes I love this shoes, they are weightless and the boost sole is just awesome, and the best part is the great style of these running shoes. Just one week using them and my knee pains are gone. I rated 4 stars because they are a little bit oversized, every other running shoe pair I have bought is size 9 but with this shoe I would need an 8 August 14, 2014
Rated 2 out of 5 by Not Worth It. From a technology standpoint, the Energy Boost 2.0 ESM is a better shoe - more support in the upper and more cushion in the midsole, plus better color choices. The Primeknit looks cool on screen, but the actual shoe was ugly. August 10, 2014
Rated 5 out of 5 by Great shoe It fits like a glove and stays snug the whole run. Great for knocking off some time from your personal best. July 27, 2014
