According to /Film, Puma has created a line of Monster shoes based on some famous Japanese B-movie characters.
Each signature shoe lists the “Skills” and “Attributes” of the monster on the inner tongues, while the outer materials are textured after the respective Rampage-ers’ armor and skin. Clockwise: Moth King (Mothra), Lizoid King (Godzilla), N/A (Mechagodzilla), Terror King (Ghidorah), Ape King (King Kong).
I'm partial to the Ghidorah and Godzilla ones...though the Mothra is very artsy. The mecha is a little old skool 80s.
