The adidas Ultra Boost 2020 ISS US National Lab Tech Indigo is part of the Ultra Boost collection that resulted from a collaboration between adidas and the International Space Station (ISS). The adidas Ultra Boost 2020 ISS US National Lab has a PrimeKnit upper with a Tech Indigo colorway. The updated 3D heel frame and 3-Stripes cage contribute to the sneaker’s lightweight construction for adaptability and enhanced support on landing. It has a special co-signed label on the tongue and ornate weaving to reinforce the toebox. The Boost midsole provides improved cushioning and offers superior energy capture and return while running. The Stretchweb outsole is constructed with Continental rubber to deliver maximum surface traction. Our experts consider the best feature is the updated PrimeKnit upper with Tailored Fiber Placement technology that provides foot support to unleash the explosive energy of Boost.
