Sustainable sneakers that can still stunt? The adidas Ultra Boost 4.0 Parley Carbon proves it is possible. With a Primeknit upper consisting of 85% Parley Ocean Plastic, an innovative material created from upcycled waste, the shoe is literally and figuratively green. The shoes also feature BOOST tooling, a Continental rubber outsole, and an NFC chip in the right shoe providing exclusive info about plastic pollution via your smartphone. If you’re looking for a pair to rock on Earth Day, bid on these today. In an ocean-inspired blue, black, and white color scheme, the shoe is composed almost entirely of recycled materials intercepted from coastal communities and beaches. For contrast, co-branding at the tongue and a matching midsole/outsole combination are presented in white.
