Eco-Friendly Materials

Looking for Eco-Friendly footwear? Meet Rackle.

The Rackle brand was built on the principle of developing earth-friendly footwear to help lessen the shoe industry's impact on the planet, one pair at a time.

Producing earth-friendly footwear was not an overnight success for us. We wanted to use materials that are both kind to the planet and also cost efficient. We narrowed our focus to plant-based materials. Continued analysis and testing lead to hemp, the source and material for what is being used in all Rackle footwear uppers today.

PLANT-BASED UPPERS.

SUSTAINABLE.

Hemp is one of the most sustainable crops in the world. It thrives by absorbing CO2, requires no irrigation and can be harvested just three months after planting. Produced entirely without any pesticides, hemp easily outperforms fiber production per hectare versus cotton. One (1) acre of hemp will produce as much fiber as 2 to 3 acres of cotton. Also, hemp fiber is softer than cotton, lasts twice as long as cotton, is water-resistant and will not mildew. Industrial hemp, used in a variety of products such as paper, construction materials and food, has essentially zero THC in it.

FEATURES AND BENEFITS.

Our 100% hemp uppers are extremely comfortable to wear all year-round. Hemp is a naturally low thermally conductive fiber, which means that it's cool when it's hot and warm when it's not. Hemp is also inherently antimicrobial – as little as just 15% hemp combined with a neutral matrix (such as polyester) will kill 99.9% of present staph bacteria.

Hemp is one of the strongest and lightest natural fibers on the planet and is resistant to degradation from UV rays and salt water. At one time, maritime sails and rigging were made from industrial hemp.

EcoPure® FOAM SOLES

The technology is in our soles. Rackle soles feature EcoPure®, a treated foam that promotes bio-degradation, but does not compromise performance, appearance or shorten the useful life of the shoe. Our EcoPure® foam soles start to work (biodegrade) when in a microbe-rich environment, such as a landfill. The only difference is that the material will degrade* in a landfill much quicker than untreated foams that make up the vast majority of shoe midsoles, up to 30-50 times faster.

As we release additional products, we'll continue to focus on sustainability and environmentally-friendly materials. Whatever materials we utilize, you can be assured that they will be ethically sourced and friendly to the planet.

 

* Biodegradation rates of EcoPure-treated materials measured according to the ASTM D5511 test method. Tests are generally conducted using 20% to 30% solids content; solids content in naturally wetter landfills range from 55% to 65%, while the driest landfills may reach 93%. Actual biodegradation rates will vary in biologically-active landfills according to the type of material used, the product configuration, and the solid content, temperature and moisture levels of the landfill.
