These are extremely rare and hard to find vintage Puma Mostro Y2K Womens Yellow Leather Bubble Sole Trainers

PUMA introduced the world to the Mostro in 1999, and it became an instant hit, balancing sport and style with an unconventional look inspired by retro sprinting spikes and surfing shoes.

These are street wear, athleisure trainers that will make a statement when you wear them. 

I purchased these in Lugano, Switzerland in 1999 never wore them. They have been tucked away in my closet and forgotten about.
