ASICS is negras forces with London-based designer Kiko Kostadinov Studios yet again. This time, though, the duo are coming together to craft the HS4-GEL-SONOMA 15-50 GTX. Reconnecting with the Japanese sneaker brand’s trail-running roots, the uppers lend inspiration from the 15-50 cross-country spike. Only it’s reworked with a GORE-TEX membrane and covered in a green sheen MONACO palette reminiscent of seascapes and scenic landscapes. The outsole, however, is detailed with the same construction as the GEL-SONOMA and promises both cushioning and traction with every stride.
