Story & provenance
Late-Decade Student Workhorse
Gelburst 23, from 2019, captured the late-2010s version of the Asics student basketball formula 鈥 steady, reliable, and targeted at Japanese school teams rather than the global performance market. It shares its core midsole approach with contemporary Gelhoop V12 and other Flytefoam-era Asics hoops. As the series' annual/biennial cadence means older generations are quickly discounted and eventually discontinued, Gelburst 23 is now a deep-cut option mostly available through Japanese used-sneaker platforms or end-of-run inventory on Amazon Japan. It's rarely recommended over more recent generations for active players, but remains a genuine basketball shoe rather than a lifestyle crossover 鈥 an important distinction given how many modern Asics silhouettes drift into SportStyle.
