The GEL-NYC GS (Grade School) sneaker sources inspiration from heritage and modern performance running styles.​ Its upper construction references the GEL-NIMBUS 3 shoe from the early 2000s and blends it with various embellishments from the GEL-MC PLUS V design.​ The tooling design is also influenced by ISS insights and developed with greater flexibility in the forefoot and stability in the midfoot to help support kids' growing feet. The design is inspired by ASICS archive models and combines the flowing lines and scalloped edges of the 2000s and 2010s.
