About the Nike Structure Plus 'Hydrogen Blue'
The Nike Structure Plus 'Hydrogen Blue' showcases double-stacked cushioning on a running shoe designed with stability in mind. A gradient blue finish is applied to the mesh upper, featuring black Swoosh branding and a no-sew heel overlay in Total Orange. The midsole combines a top layer of ZoomX foam with a bottom layer of ReactX foam, resulting in a smooth and responsive ride. Nike's innovative midfoot support system, borrowed from the Structure 26, wraps both the medial arch and lateral heel to provide enhanced stability through the runner's stride. Underfoot, high-abrasion rubber in the heel offers enhanced durability, while soft rubber in the forefoot delivers improved flexibility.
