One of the more significant innovations in running footwear last year was the adidas’ new Boost midsole material. Though much of the hype surrounding Boost was simply that – hype – there’s no denying that the material offers a unique underfoot feel with plenty of rebound and bounce.
In its first year, the Boost technology was originally limited to just three models: the Energy Boost, the cushioned and supportive adistar Boost, and our favorite of the three, racing-oriented adios Boost. This year, adidas is indeed all in with this new midsole, as we will see the Boost treatment make its way into most of adidas’ other running shoe models, including their popular lightweight neutral trainer, the adizero Boston.
Though much of the Boston 5’s midsole consists of the Boost material, the shoe retains traditional EVA in the forefoot as well as in a thin layer extending through the heel, providing a responsive and performance-oriented underfoot feel. adidas anticipates that runners who typically run in the Energy Boost or the Supernova Glide will be able to easily transition to the more nimble Boston for their faster paced runs.
Though the addition of Boost is clearly the big change in this update, this update looks to feature a few relatively minor changes as well. Namely, the upper will feature a more minimalistic design with fewer overlays for improved comfort, while the outsole will feature full ground contact, delivering a more consistent ride from heel to toe as well as increased traction. In all, we expect to see a slight drop in weight with this update, a welcome change that will keep the Boston alongside its close rivals in the Asics Gel Excel33 and the Brooks Launch.
The adidas adizero Boston 5 will be available September 2014.
