One pair of size 42 Men’s VivoBarefoot Ultra III shoes, made with Bloom’s patented algae technology is said to return 57 gallons of clean water to habitat and reduce 40 balloons-worth of CO2 from the atmosphere.

Leading London-based barefoot shoe company VivoBarefoot has announced its partnership with Meridian, Mississippi-based Bloom, which uses algae biomass harvested from freshwater sources around the world to make EVA foams out of a non-fossil fuel for the first time. VivoBarefoot shoes will be the first full shoes to use the material and will be available for purchase in the summer of 2017.

The VivoBarefoot Bloom collaboration will start by using the BLOOM algae-EVA foams in the Ultra line of amphibious adventure shoes. A single pair of men’s size 42 VivoBarefoot Bloom shoes is claimed by the manufacturers to return 57 gallons of clean water to habitat and reduce 40 balloons worth of carbon dioxide from the atmosphere.

“Our goal is to deliver the most performance-driven materials in the most environmentally-responsible manner,” said Mike Van Drunen, CEO of Bloom. “It is a goal we constantly strive to improve upon, and we are excited to collaborate with VivoBarefoot on the new Ultra line.”

Founded in 2012, VivoBarefoot is a global barefoot shoe company, offering men’s, women’s and children’s shoes for everyday wear. In addition to encouraging people to get closer to nature, the company prides itself on its sustainability practices.

Bloom is a performance-based materials manufacturer, founded in 2015, that offers the first sustainable alternative to the synthetic and petrochemical foams prevalent in today’s market. Using algae biomass, the company states, helps offset the significant use of petroleum ingredients found in conventional flexible foams.

“This is a true revolution for the footwear industry with the first plant-based alternative to the petro-foams in ubiquitous use,” said Galahad Clark, founder and MD at VivoBarefoot. “We are thrilled to be the first company to use Bloom in our shoes and further our mission to make the perfect shoe…perfect for feet and minimal impact on the planet.”
