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 colour 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.
