Rens waterproof shoes are made with used coffee grounds 

By Angela Garrity, Guest blogger 

Entrepreneurs in Helsinki, Finland know literally what it’s like to keep running on coffee. Son Chu and Jesse Tran have created sneakers from used coffee grounds in their brand, Rens, the World Economic Forum reports.

Rens is the world’s first waterproof, breathable, eco-friendly and odor-resistant shoe made from coffee, the Kickstarter project states. Every pair of Rens is constructed from 300 grams of locally sourced and recycled coffee grounds and the equivalent of 6 recycled plastic bottles. All coffee used in the production of Rens is post-consumer waste that would otherwise end up in landfills and contribute to climate change, which is good news for the planet.

The used coffee grounds are used to create an incredibly flexible yarn. This yard holds some pretty cool foot fashion technology such as allowing for odors to be trapped in micro-pockets, antimicrobial for great disinfectant use, UV light blocking properties to keep colors staying vivid and a quick dry outer layer.

Sadly, the shoes do not smell like coffee, but look on the bright side, pessimists. Being made from recycled coffee grounds means the anti-odor properties ensure they won’t smell like anything at all. That keeps everyone happy.

Rens are estimated with a delivery date of November, according to their Kickstarter page, so consider adding these to your holiday wish list. Versatility is key with Rens and they just might help you kick the holidays into high gear.

Perfect Little Beans

Chinmey Hill Coffee uses specialty-grade beans with zero primary defects (such as black beans or sour beans) and less than five secondary defects (such as broken beans). This is important because primary defects will greatly affect the taste of the coffee. Having zero defects allows the coffee to be the most optimal flavor.

Window for Optimal Flavor

Chimney Hill Coffee ships our coffee the same day it was roasted, so you will receive it before it enters the window of optimal flavor.  This means you’ll never miss the opportunity to enjoy the coffee’s peak flavor.

Coffee Ratings

Coffee undergoes many scoring processes by professionals who achieved their Q Grader certification. Coffee is first graded when it’s green. If there are defects the coffee is determined to be “not-specialty grade”. For those coffees that pass green grading, they are sample roasted and cupped. (Cupping is the official term for critically tasting and scoring coffees. The official cupping form is standard worldwide, and where the 100-point scoring system comes from.) A coffee’s dry fragrance, wet aroma, flavor, aftertaste, body, acidity, balance, and overall impression are taken into consideration while uniformity issues and defects, will lower the overall score.

Specialty Coffee

Specialty coffee, coined by Erna Knutsen in 1974, refers to a coffee that receives a quality grading score of 80 percent or higher. While “premium” or “gourmet” seem like they’re synonymous with “specialty,” they simply are marketing terms with no defined standards. Specialty coffees are grown in specific and ideal micro-climates, and have distinctive and unique flavor profiles, with little to no defects.

Third-Wave Coffee

We’re currently in the third wave of coffee. The first wave of American coffee put pre-ground, vacuum-sealed cans in kitchens across America. The second wave started with the late ‘60s introduction of Peet’s coffee (by Alfred Peet) through the proliferation of Starbucks. The third wave of coffee focuses on origin transparency, nuanced flavors, and artisan roasting. The term “third wave” is synonymous with specialty coffee.
