The US4-S Gel-Terrain is from ASICS's sportstyle range rather than their running line. Chunky trail-inspired design with GEL cushioning in the heel. The outsole has aggressive grip patterning but this is more of a fashion shoe than something you'd take up a mountain.
What's the US4-S line?
It's ASICS's collaboration-friendly lifestyle range. Same GEL technology as their performance shoes but designed to be worn casually. Suede and mesh upper on this colourway. From the ASICS outlet so expect limited sizes.
