Adidas' Boost cushioning tech has been a revelation in running over the last year, and now the Three Stripes return with the re-up, the Pure Boost 2. It's pretty similar to its big daddy, but there are a couple of nice alterations, with the mesh game stepped for enhanced breathability. The Three Stripes are also cut into the mesh in the men's model, while the women's version will maintain the same augmented style as the OG. The Pure Boost 2 is available in three colorways for men, including Core Black/Solid Grey, Collegiate Navy/ Zero Metallic and Onix/Silver Metallic/Grey, and four colorways for women including Flash Orange/Core Black, Solar Pink/Core Black, Core Black/Solid Grey and Onix/Silver Metallic/Grey. It's available now from adidas retailers.
