Ocean plastic continues to harm delicate ecosystems around the world and companies like Parley have offered a helping hand to turn that harmful waste into sneakers. Parley's latest collaboration has them turning plastic trash into the upper for adidas' high-tech Alphaedge 4D. The sustainable upper sits atop a unique midsole that's created using Carbon's Digital Light Synthesis, a 3-D printing method that turns liquid resin into a high-performance midsole platform. 

The shoe will be available from May 31st to June 8th via the adidas app.
