ASICS developers and the Kiko Kostadinov Studio reconnected with our trail running roots to create the HS4-S GEL-SONOMA™ 15-50 GTX sneaker.Inspired by outdoor exploration,this shoe’s color palettes reference scenic landscapes and seascapes.For the upper,this style borrows inspiration from the 15-50™ cross-country spike.It’s reworked with a GORE-TEX™ membrane to shield the elements and keep your feet dry in wet conditions.The tooling features the same midsole and outsole construction as our GEL-SONOMA™ trail shoe.With advanced cushioning and traction,this design is functional for adventurers hiking in the forest or navigating city streets.
