Here's how to win limited edition Adidas sneakers made out of recycled ocean plastic

In April, Adidas and advocacy group Parley for the Oceans teamed up to create a 3-D printed sneaker prototype made out of plastic and illegal deep-sea nets found in the ocean. Adidas turned these materials into technical yarn fibers that can be used in its sneakers and clothing products.

Now, the two companies have released 50 pairs of the shoes, which use the material in the upper part of the sneaker. The product was unveiled on June 7, a day before World Oceans Day.

The limited number of shoes cannot be bought and are instead being given to winners of a contest for Parley's A.I.R. initiative to end ocean pollution.

To be entered to win a pair of sneakers from the collaboration, make a video pledging your commitment to keep the oceans clean, upload it to Instagram, and tag Adidas and Parley in the caption with #ParleyAIR. The contest runs until July 31.

According to Adidas, the company will incorporate Parley's own brand of ocean plastic into one of its popular footwear lines later this year. They also said the current shoe release is "the first in a series of products that adidas is now able to produce using Parley Ocean Plastic."

Here are what the Adidas x Parley shoes look like:
