First impressions

The brand's most popular model, the Ultaboost sees an update which increases it’s cushioning by 6% over the previous edition making it the most cushioned of the Ultraboost line to date. It packs the Boost material into now what appears like many ‘maximal’ type shoes, with a deep stack-height and almost bulging midsole shape.





It can’t be denied, the shoe is very cushioned, particularly noticeable for heel strikers, where the Boost cushioning simply soaks up any impact with ease.

This model differs a little from previous editions though thanks to the addition of a ‘Linear Energy Plate’ this redesigned version of the brands ‘Torsion’ plate extends into the forefoot more and becomes stiffer to increase responsiveness. It does indeed feel stiffer under the forefoot, noticeably so and seems a harsh contrast to the soft nature of the Boost material, rocking the foot forward aggressively as you shift from heel to toe. I found it took a few runs to settle down into the feel of the ride, but it became a good option for runs of varying pace able to adapt to the demands of both a heel and forefoot strike.


The upper retains the sock-like knitted construction and one-piece design. It’s well made and along with the 3-stripe lace cradle supports the foot well.


Traction comes from the familiar Continental rubber outsole and can’t be faulted, offering a fantastic non-slip confidence inspiring grip on any surface in any conditions.


For fans of previous editions of the Ultraboost range, it’s certainly the best yet!
