Our Verdict

Adidas no longer makes the Pure Boost X.

The female specific Adidas Pure Boost X Training takes the cake for the most unique and innovative design feature: its floating arch. The floating arch design is just that, an arch that isn't connected to its Boost foam. The training specific shoe fits like a glove; this is in large due to the floating arch and the added bounce from the Boost foam sole, which makes for a smooth ride. We enjoyed testing this fun new take on an athletic shoe. During short jaunts on the pavement or sessions at the gym, the snugness was a sure pleaser.

PureBoost X is a awesome shoe for runners with a neutral gait who are looking for a training specific shoe.


The cushion "Boost" technology adds bounce via high responsiveness on road runs and never disappointed during intense training sessions. It's evident that Adidas put a lot of thought into the Pure Boost X Training and pitched it as a training specific shoe. With the design features of the easy rotation pivot-point rubber outsole and the Boost midsole, this trainer earned a spot in our hearts.

We turned to the Boost for light runs on pavement or long walks, as the absence of tread does not respond well to gravel roads or hill climbs. A higher performing minimalist shoe that is more adept for gravel roads or hill climbing conditions is the Salomon S Lab Sonic, which is similar in weight, but equipped with more tread. The fast receptive design of the Pure Boost X didn't feel sluggish during training sessions, which earned it a 6 out of 10 in this metric. The highest rated contender was the minimalist Salming Race 3; it was the only pair that scored a near perfect 9 out of 10, due to the RunLite midsole.

Landing Comfort

Initial runs in the Pure Boost felt awkward and definitely took some getting used to. After striking a balance and discovering where the shoe performed the best in everyday activities, the supportive and tight feeling of the Pure Boost X was well received. The foam presented exceptional landing comfort, giving ample feedback on the flats, and providing enough comfort to move with ease during forward motion. The Nike Air Zoom Structure 20 and Salming Race 3 provided similar landing comfort, each scoring a 7 out of 10, compared to the Boost's 7.

Upper Comfort

The glove like aspect of the Pure Boost X is enhanced by the combined upper materials of the mesh, textile, and synthetic, which all mold to the foot. The materials of the upper were comfy enough to wear without socks; yep, we went there. The sock feel was similar to that of the Salomon S Lab Sonic, which was designed to cradle the foot, providing an accurate and secure fit. If you're after a plush contender, the New Balance 860 V7 has the softest upper design, earning the only 10 out of 10 in this metric. In comparison to the Pure Boost X, the New Balance 860 V7 did not have the secure, snug fit that we felt the Pure Boost offered.


The Pure Boost X midsole hugs the foot and fits like a sock. This floating arch forms to your arch, allowing the arch support to move naturally. The Boost is efficient and allows for easy transition through the gait cycle. We felt that the design of the sock-like arch support was an interesting innovation, though it requires an adjustment period before reaping the full benefits that are offered.

The Boost, alongside the Saucony Hurricane ISO, were the two contenders that scored a 4 out of 10 for stability - the lowest in our tests. If you're looking for ample support, the X might not be for you. Instead, consider the Brooks Glycerin 14 - Women's, the only contender to score a 9 out of 10 in this metric, or the Nike Air Zoom Structure 20, Brooks Ghost 10 - Women's, New Balance 860 v7, or the Asics Gel-Cumulus 18, all scoring 8/10.


The material of the Pure Boost foam was durable and we only experienced average wear. The non-marking rubber outsole had reasonable grip, and we found that this contender showed sensible wear for the miles that we applied. If these shoes were only used as a trainer, we could see them lasting for a considerable amount of time. We did observe one downside; the mesh on the side, which allows for venting, appeared to wear faster than the more durable materials that can be found on the shoe itself. In terms of durability, the Hoka One One Bondi 5, Brooks Ghost 10 - Women's, and Brooks Glycerin 14 - Women's took the cake for durability, each bringing home a 9 out of 10.


The mesh upper of this contender allowed for even breathability, wrapping around and underneath the mid-foot. The wrapping of the mesh provides a supportive and snug fit which also allows for ventilation during long runs, especially on hot days. The side venting of the mesh is a nice touch that combines well with the textile, synthetic upper, allowing this shoe to withstand colder temps, as well as hot days when baking in the sun on a long run. The ventilation on the Pure Boost was comparable to the Salomon S-Lab Sonic, but would be a better colder weather option.


This shoe is light, coming in just over 6.5 ounces in a women's size 8, still among one of the lightest shoes in our group. For those looking for a different shoe, but with the same weight, the Altra Intuition 4.5 is a fine alternative. The Pure Boost X landed high in this metric, scoring an 8 out of 10.

Best Application

This pair of running shoes is best on short runs that are primarily on the roads or a track. As a training shoe, the X was a decent shoe for use at the gym, or on a walk during rest days.


The X retails for $120. This light and fast sneaker is towards the cheaper end of our fleet and is a good option for workouts that involve more than just pounding the pavement. These are excellent shoes for a light training session indoors or a stylish option to be worn out on the city streets.


Always remember that running should be fun.

The Pure Boost X is made for runners with a neutral gait who are looking for a training specific shoe. We thoroughly enjoyed the responsive ride and sock-like upper fit. The cherry on the top is that these running shoes are also quite stylish.
