The Asics Gel-Quantum Kinetic "Birch/Dark Taupe" is a colorway of the casual shoe loosely inspired by ASICS’s work with fashion designer Kiko Kostadinov. The Asics Gel-Quantum Kinetic features elements from the Gel-Nimbus, the Gel-Kinsei, the Gel-Kushon, and the Gel-Kinetic models. As for the “Birch/Dark Taupe” colorway, the two colors land on the shoe’s techy, futuristic design features across the mesh and synthetic upper.
