This is a collaboration shoe between ASICS and KIKO KOSTADINOV. Size: 27cm In excellent condition, worn a few times. The insoles are unused as I used different ones. The base model is GEL-QUANTUM, but the upper incorporates designs from GEL-TRAIL ATTACK 5 WR, GEL-TRABUCO 13, and GEL-TIOGA, reflecting a trail running-inspired structure. The midsole uses SCUTOID GEL technology, emphasizing the contrast with the upper. The name "KISO" in the model name is derived from the Kiso Mountains.
