Earth Day 2021 brings to the fore the discussion about our efforts to restore the Earth we share. One of the key questions in the ongoing discourse is: how do we reduce our consumption? In some attempt to answer this question (short of closing shop), many of the brands we know and love have started to make the effort to apply sustainable technologies to their sneaker and apparel production.

The good news is we know 66% of sneakerheads are more likely to buy something if they knew it was made sustainably. So here’s a look at all the sustainable technologies your favorite sportswear brands are using in their sneaker manufacturing lines now.

Nike Grind – Instead of tossing waste materials and unsellable products into landfills, Nike separates them and breaks them down into a new material called Nike Grind. Nike has found multiple ways to utilize Nike Grind, from embedding them in outsoles to using them to construct in-store features.

Crater Foam – A midsole construction first seen on the Nike Space Hippie line. Crater Foam is made of 12% Nike Grind rubber and a mixture of foam materials. This combination promises to be sustainable, lightweight and responsive, making it ideal for lifestyle sneakers.

BCI works towards reducing the environmental impact of cotton production and improve livelihoods and economic development in cotton-producing areas.
