The size us15s fit a mens 12, these ones are very tight compared to the other pair i have (blue platform chunky heel allstars) and would likely fit a narrow foot or a size 11 much more comfortably the incline is very aggressive and the platform is quite narrow, likely meant for people more comfortable in heels, but i still love them... and the flame is a very shiny and reflective blue/green/purple chameleon material, the pictures dont do justice to how shiny it actually is
