When it comes to adopting eco-friendly habits, there are plenty of things we can do to be kind to the earth. Up until recently, though, our sneakers didn鈥檛 offer many ways for us to be environmentally responsible. We need them in order to work out, of course, and when they鈥檙e dust, they鈥檙e dust. But now, Adidas has introduced a prototype shoe whose upper is made of plastic salvaged from the ocean, consisting of yarns and filaments from illegal deep-sea fishing nets. Designed by Alexander Taylor and launched in tandem with the Parley for the Oceans initiative, the shoes are part of an effort to encourage the creative reuse of ocean waste.

What鈥檚 more, the shoes are built on an Adidas Boost sole, which promises up to a 20 percent boost in performance when worn. So not only are they made of far more sustainable materials than any other gym shoes, but they also literally put a spring in our step and some extra oomph in our workouts.

Though it鈥檚 just a concept shoe for now, Adidas says it will be scaled up into a widely available consumer product next year, along with other eco-friendly sportswear pieces. In the meantime, the brand鈥檚 been making other strides for the environment, like their recent decision to do away with plastic bags in stores. It鈥檚 also piloted some take-back programs for used Adidas shoes, which are either donated or recycled instead of ending up in landfills. Personally, we鈥檙e digging the move toward keeping things eco-conscious from head-to-toe.
