Men's Asics Ub5-s Gel-nimbus 9 - Gray - Low-top sneakers The ub5-s gel-nimbusTM 9 sneaker was created by the kiko kostadinov studio. They were inspired to update the heritage trainer's technical details with a series of archived trail shoe features. Elements from the gel-trail attack shoe's line detailing are met with lace-like mesh underlays on the upper. Meanwhile, the sneaker's coloration references the look of galaxy matter that coincides with the design's futuristic influences. The segmented midsole's gelTM technology inserts in the heel and forefoot are designed to increase shock absorption. This makes the shoe more adaptable in different surroundings.
