The adidas Forum is an '80s B-ball icon, and this pair brings on the retro vibes. See the muted colors and famous X design? Yep, we're talking hardwood style at its finest. But it's not all about the past here. Adidas teamed up with Parley for the Oceans to reimagine the design with the future in mind. The tongue webbing and heel strap are constructed using upcycled plastic waste, plus there's a partially recycled BOOST midsole for endless energy.
