If only more comapanies were willing to step up and do something useful with the waste/ non biodegradeable products that end up in the ocean. I would buy these despite the steep price. Of course it helps if this stuff didn't end up in the ocean in the first place.
"The sneakers are made in collaboration with Parley for the Oceans,
an environmental group that wants to draw attention to pollution in the
ocean. Each shoe’s upper (the part that goes over the top of the foot)
is made from 5 percent recycled polyester and 95 percent waste plastic
dredged from the ocean around the Maldives. Each pair of shoes contains
11 plastic bottles, and most of the rest of the sneaker (including the
heel, lining, and laces) is also made from recycled material."
