Indigo Storm/Hydrogen Blue/Summit White gives the Nike Flex Train a dark upper and a much lighter foundation. Blue mesh runs from the toe to the collar, crossed by a white Swoosh and conventional laces. A pale blue band follows the heel above the tall white rear midsole. From underneath, matching blue rubber surrounds a lighter center, and closely spaced cuts break up the front edge. Nike's regular US listing price was $80 on September 22, 2026.
The shoe combines a mesh upper with a full-length foam midsole. An elastic heel band provides additional support, while cutouts in the rubber outsole and narrow forefoot slits allow the base to flex. The rear sole rises higher along the side than the front, creating the curved profile visible in both product views. These construction details suit the model's general workout role.
