Running Warehouse was kind enough to provide Road Trail Run with a pair of the Adios Boost at no cost for testing and review.
The adios Boost 1 (review) was my 2014 shoe of the year. I ran all my half marathons and road races in them and even easily handled a 25K trail race. A fantastically versatile shoe with a great upper and wear like iron Continental rubber outsole, I have 2 pairs each pushing 200 miles with only minor outsole or upper wear.

The secret to "controlling" the soft Boost material and aligning the foot in direction of travel is the adidas Torsion System of TPU plastic plates. Starting with a very effective vertical piece on the medial side of the heel to reduce early pronation, continuing with at truss at mid foot to improve mid stance stability and then running with 2 long strips laterally and medially under the outer rows of lugs with a shorter center of the fore foot strip Torsion is what keeps the foot aligned and moving to toe off spring board, even when tired. All of this is designed to break world records but I can say it sure works for me as well. There is a sense of stability, forward direction, alignment, and snap not felt in many other lighter racing shoes. No apparent changes from previous models.

The outsole is where the significant changes between AB1/AB2 and AB3 occurred. Gone is the Quick Strike plate with nubs of firm plastic glued to a sheet in the center of the forefoot of both the AB1 and AB2. Quick Strike is replaced by a fuller coverage, and thus slightly softer more cushioned layer of hard wearing Continental rubber arrayed in pods.
This fuller coverage rubber should help dissipate shock a touch better and it sure feels that way when I compare the two on the road. Generally the outsole pattern changes from the tire tread like set of grooves on the AB1 and AB2 to pods, which leads to a more personalized somewhat softer feel on contact for me.

The outsole of the adios Boost 2 (below) is identical in appearance to the adios Boost 1. The only changes, colors.

Don't be scared that this is the world record setting marathon shoe!
Unlike many racing "flats" the adios Boost is well mannered, protective and fun at any speed. It can easily be a single quiver shoe for lighter faster runners or a speed and any distance race shoe for most. Even a fine choice for casual runners wanting a low profile light shoe with great road feel.
While the forefoot cushioning is thinner than most trainer at 13mm, the rebound of the Boost midsole and the relatively soft yet durable Continental rubber, now with fuller coverage, make the ride firm yet still very comfortable. The heel is fantastic, well cushioned yet also firm and stable and easy to move off of at even moderate speeds. This said I have found the adios Boost really comes into its own in terms of a smooth transition at paces faster than 10 minute per mile.
If you have never tried a Boost midsole shoe the rebound and energy return is noticeable. True to its purpose as a race shoe, the adios has a distinct toe spring but unlike many race shoes it is stable, well cushioned and directed due to the Boost and Torsion System.
While I prefer the original AB1's more fitted upper for its support, which when combined with the Torsion system made the adios not only a great road shoe but a very able trail racer, the new upper is just fine, more relaxed and comfortable particularly for those with wider feet and for longer run road use.
Not an in expensive shoe at $140, the durable outsole will last as long or longer than those on many trainers and its versatility can eliminate the need for several other shoes. We do wonder about the relative durability of the upper.
Adios Boost 3 to Boston Boost- The Boston Boost has 3mm more cushioning at the heel and forefoot and 0.6 oz more weight. It is stiffer at the very front of the shoe where the EVA midsole layer is longer than adios. The Boston fits snugger at the ball of the foot than the adios Boost 3. It lacks the adios medial plastic Torsion piece and as a result, as a heel striker, I found Boston's heel soft and a bit less stable than the Adios. Boston leans more towards being a trainer.
Adios Boost 3 to Salming Distance 3- The Salming Distance 3 (review soon) is most similar to the Adios Boost of the shoes I have run in recently. It also has a Torsion Efficiency Unit similar to adios Torsion plastic under the mid foot and very similar outsole configuration. Its upper has a generally similar relaxed fit. The ride is similar with a very decent rebound effect from the RunLite midsole and a noticeable and directed toe spring. It has 4mm of additional cushion at the forefoot with 1mm less at the heel for a 5mm drop and weights 0.7 oz more.
Adios Boost 3 to Saucony Kinvara 7 (review). Very different rides from these 2 shoes. The 4mm drop Kinvara is stiffer overall with more forefoot cushion, 6mm more of it, for a shoe weighing and having the same heel height as the adios. While not as snappy a ride, it is stable and forgiving, the Everun (a TPU similar to Boost) in the heel providing a heel cushion similar to the adios. The Kinvara upper's Pro Lock mid foot system and narrower toe box with overlays is snugger overall. Kinvara may be a better marathon choice for most mere mortals when sized up a half, adios a better short race choice.
Adios Boost 3 to Hoka One One Tracer (review)
The Tracer is firmer and stiffer overall. Tracer has 7mm more forefoot stack but the forefoot foam is considerably firmer than Boost. Nod to the Tracer's upper, the best fitting of any 2016 race shoe for me. I would run a marathon in the adios Boost 3 before the Tracer.
Sam's Score: 4.8 out of 5
-0.05 for weight
-0.05 for lighter wider upper, a bit less of a dialed supportive fit which made it AB1 a great trail racer.
-0.1 for thin forefoot for marathon purpose.
