Sex toys and shoes? Try, sex toys IN shoes.

A little streetwear label has partnered with a giant in the adult toy industry to create a shoe derived in part from unused, defective amusements that come off the manufacturing line as misfits.

Looking a lot like Merrell’s popular Hydro Moc or Yeezy’s Foam Runners, Plastic Soul is about 15% sex toy. The rest is non-bleach EVA, a petroleum-based foam that’s difficult to recycle.

The shoe is the brainchild of David Teitelbaum, founder of Rose in Good Faith, and Chad Braverman, chief operating officer for Doc Johnson, the adult toy company his father founded in 1976.

More than two years in the making, Plastic Soul has yet to create the buzz of a Yeezy or the kicks of other titans in sneaker culture. And it doesn’t particularly live up to its own marketing hype as a major sustainable option, but the two Los Angeles businessmen are proud nonetheless.
