About the ASICS Gel Sekiran 'Green Gecko'

The ASICS Gel Sekiran 'Green Gecko' makes use of a bright green mesh upper with no-sew overlays in a dark forest green hue. Metallic silver trim outlines the signature stripes, matching the synthetic leather detailing that reinforces the forefoot and heel. The tooling is borrowed from the Cumulus 17, highlighted by a lightweight foam midsole with visible Gel inserts in the forefoot and heel.
