The UB5-S GEL-NIMBUS™ 9 trainer was designed by the Kiko Kostadinov Studio. They were inspired to update the technical details of the athletic shoe with a range of original trail shoe features. The details of the GEL-TRAIL ATTACK feature silk-like mesh underlays on the upper. The sneaker also features a galaxy design that coincides with the design's futuristic influences. The segmented midsole uses GEL™ technology at the heel and forefoot for extra shock absorption. As a result, the shoe adapts more easily to different environments.
