The adidas Solar Boost, was inspired, at least in part, by NASA engineering and is one of the new lightweight running shoes (295 grams - 10.4 ounces in a men’s 8.5 UK). According to adidas, the shoe uses data-driven Tailored Fibre Placement that implements Parley material (recycled ocean plastic) within its fibres at the midfoot for support. The shoe is precisely stitched and constructed using data from the Aramis system motion capture system, and the shoes are available in a wider fit with a counter designed to allow free motion of the Achilles tendon.
By comparison, according to the manufacturer, tests conducted by independents, showed the adidas Solar Boost gave higher energy return with each stride than the Nike Epic React Flyknit, which was attributed to the cushioned Boost midsole, supported by the Stretchweb outsole, used for extra traction. The shoe has a new mesh upper, made of Parley yarns, and connected to the sole via the brand’s patented Solar Rail. This plastic-like layer runs along the sole and gives support for your foot, and works in partnership with the Torsion Bar stretching from heel to forefoot.
