Asics continues to evolve its classic Gel-Kayano Trainer from the '90s, with the latest update being the most radical yet.

Feast your eyes on the Asics Gel-Kayano Trainer Evo "Chameleon" pack, which, as its name suggests, is highlighted by color-shifting uppers.

Each of these Asics Gel-Kayano Trainer Evos is built with a stretch mesh upper that changes colors depending on the angle from which it's viewed.

Available in "Gecko Green/Guava," "Blue Print/Orange," and "Medium Grey/Guava," these are priced at $120 apiece and can be found from retailers like Feature. Check out the color effect in action below.
