Here is an update on some of the materials and construction techniques we hope to be working into our line moving forward. This post is also essentially Part 3 of a series I am writing on sustainable footwear here on our blog. Enjoy!

Rice Rubber Outsole: This stuff is amazing. The outsole is the very bottom of footwear, the part that connects with the ground. Most traditional outsoles are made from rubber or PU (polyurethane). Rice Rubber is a blend of several happier ingredients. It’s a base of natural latex rubber mixed with SBR or Styrene Butadiene Rubber. SBR has been used for over 60 years in all sorts of applications such as tires, shoes, and gaskets. The blend is necessary for durability and longevity (Remember – durable footwear has a longer useful life = fewer pairs need to be manufactured). Rice husks which are a byproduct of the food industry and typically discarded after harvesting are then mixed in with the rubber. The rice husks displace a good portion of the rubber needed as well as add strength to the mixture. Similar to how gravel is added to cement to form concrete. The resulting product is not only a more eco-friendly alternative to traditional rubber soles, but it looks darn cool!
