A close-fitting, lighter-weight shoe geared toward distance runs, the adidas adizero Boston 3 features moderate cushioning with a semi-firm ride.

Details:

Worthy of its marathon name, the adidas adizero Boston 3 is the perfect choice for a light, long distance trainer. Adidas has lowered the stack height, bringing you lower to the ground to feel the road every step of the way. The decoupled heel adapts to the ground for a smooth ride, and the forefoot springs back with plenty of energy return at toe off.

Comments: I have close to 300 miles on these shoes. There is plenty to love but a couple of important details will stop me from buying another pair. What I like: Love the snug fit. The upper material is sturdy but light. The laces are the flat plain cotton ones, which I prefer. The shoe feels much more structured that I expected for a light trainer. The sole has fantastic grip. It's a durable, no-frills good quality shoe; unfortunately that is becoming a bit of a rarity in shoes these days. Great job on that. What I don't like: It's too firm on the mid/forefoot for long runs, and it has a few inches too many on the heel. That's it, other than that it would be perfect for me.

Comments: I LOVE these shoes. It's my second pair. My first one is from June last year, and it still holds up. The second one is better, has a roomier toe box. I don't know if it's a glitch in the manufacturing that the pairs are different, or if it's an improvement in the model. Same model, same size. Anyway, I love them. They're comfortable, light and tough. You can run many miles at once in them if you have no problem with neutral shoes, and moderate cushioning. I run from 6 - 10 miles and even 13 + and these shoes take it. Last year's pair is still holding up despite running through winter. A++

Comments: My favorite road training shoe is the Adidas Tempo 4 which is a bit heavy but the stiff midsole never leaves my feet sore from overflexing. I've owned five pairs and would continue the trend if the Tempo 5 were the same, but its design has changed. So I was looking for a similar trainer and even tried out the Nike Flyknit line, but I wasn't impressed. The stack dimensions of the Boston 3 looked ideal and maybe, I thought, the mid-sole in the fore-foot would be stiff enough to limit toe flex. I was instantly pleased within the first 100 meters, and had found my shoe by the end of the run. It feels just like a lighter, faster version of the Tempo 4, with a confident fit and a seemless roll from heel to toe, I never suffered any soreness from the reduced weight. It didn't take long before I ordered another pair to replace this pair after they've given me miles of good service.

Comments: I can only say, if you are going to run a marathon, these are the pair of running shoes you have to get, I ran my first Marathon using these and I didn't have any issues whatsoever. I would buy another pair for my next marathon.
From: Fabian, San Jose, Costa Rica

Comments: I have to mention these shoes are really firm or hard, especially if you are a midfoot/forefoot striker. There is a disjoint, softer heel cushion which provides very little use for non-heel strikers but may help cushion for heel strikers. The sizing is small by half so if you wear 10.5, get 11. I've recently tried about a dozen different shoes in search of finding one that "works" and the Boston3's are by far the most firm shoe out of any ones I've tried (Mizuno, Brooks, Saucony, Nike, NB). I would prefer to run in a pair of Nike Matumbo spikes on a medium hard track (for a long run of 2 hrs) than using these on the paved road again. The upper is fairly low profile and "thin" with perhaps minor lacing issues for some (that is, could be a little snug around the ankle which may cause irritation). Too firm for me but may use on grass/soft surface runs in the future.

Comments: 10k first outing today and I come away quite impressed. These are my second Adidas, the first was the light weight Feather which runs fast but may have contributed to a small inside ankle injury, thus my reason to look for another shoe for longer runs. This is a stiff shoe with good support throughout and I just love the toe-off feeling. I went half a size up.  I normally wear EU42 which was ok but I did get the feeling that I needed to half size up if I were to wear this on a long run, which I intend to - feet always swell a little. It's quieter than the older feathers and I won't call this "Adidas". They're "Boston 3s".

Comments: I've put over 360 miles on my Boston 3s. I still have a pair of Boston 2s with nearly 600 miles on them and they're still going. The Boston 3s do feel a little lower and lighter than the 2s. Can use them for long  runs and faster work such as tempos. A great all-around trainer that is light, responsive and durable. I also use the Adios 2 for tempos, track work and races. I also run in Kinvaras but sometimes my calf, achilles, or heel gets a little sore in those. I stick to the Bostons for a while and the aches go away. I did have to mess with the lacing on the Bostons to avoid some pain on the top of my foot but nothing real serious. Just a great shoe. And a good value since I can get a lot of miles out of them.

Comments: Great shoe, I'm on my second pair. Similar to other its lightweight, flexible and just enough cushioning. I slightly over-pronate, and no problems whatsoever. I've run with Asics GT's, Nike Pegasus and Zoom Elites; this is my shoe of the long haul
From: Gilbert, New York

Comments: This is my first pair of Adidas running shoes, and I am enjoying the ride. These shoes are very responsive with just the right mix of cushion and firmness. I feel and run fast in these shoes and plan to purchase another pair when these turn into yard work shoes. My only problem is that the left shoe rubs my big toe, but this was fixed with a band aid or moleskin. I like the shoe that much to put up with a minor inconvenience.
From: Adam, Lancaster SC

Comments: I love this shoe. Have never had Adidas but thought I would give it a shot after wearing mainly Brooks shoes for the last several years. It's a little on the firm side but not as terrible as some might tell you. It'll definitely hold up for long runs. Fit is nice and secure. Shoefitr said to go a half size up, but I found that too big. True to size for me. Maybe very slightly small, but I wouldn't go a half size up unless you have to do that more than occasionally. Good flexibility as well. 12mm drop, but honestly it is light enough and a relatively low build for a trainer that it is not a big deal.

Comments: I agree with Eric from San Diego on every point, except I actually like the yellow/red model.Shoe fits like a glove, provides enough room in the toe box, no unnecessary bulk, great laces. At first, cushioning may feel a little firm (and fast), compared to softer shoes, but I've been surprised by how well my legs have felt, training and running in half marathons, even when running on concrete. Cushioning is effective from heel to toe off. I'm in my 50's, recreational runner (20-35 miles a week), 150 lbs. IMO a great all-round training and race day shoe, even for the those that pronate slightly.  Prior models: Ravenna, Waverider 14, Nexus 5, and Precision 11.
From: Keith, Kansas, USA

Comments: The canary yellow/electric orange Boston model may just be the ugliest shoe ever made, which is a shame because many people who would have otherwise liked this shoe won't consider it. It has good cushioning without bulk, solid upper without excess weight, great snug fit through the heel and arch but a roomy toe box. Just a very good basic neutral trainer, which is harder to find than it should be. Wear them on your night runs and you will never get hit by a car, guaranteed. I'm not sure who is in charge of picking color schemes at Adidas right now, but they need to dial it back. A lot. Even the two-tone blue model is ugly, but the canary yellow one looks like some sort of joke/prank. What were they thinking?
