2015 may have been the year of the adidas Ultra Boost, but 2016 is already looking promising for the Three Stripes’ most popular running shoe. The Ultra Boost gets upgraded for the new year, with the Ultra Boost ST, which is actually designed to be a version of the shoe with added stability. The most technically advanced running shoe from adidas yet, the Ultra Boost ST features an even sleeker and faster look than the original model, and utilizes a special ‘tuned energy’ column on the medial side’s midsole to help overpronators stay stable throughout their run. The Ultra Boost ST is available now in this clean grey and green Primeknit colorway now at adidas.com and select adidas Running retailers.
