To reduce the size of one's carbon footprint, ecologists recommend turning off unused lights, composting biodegradable foodstuffs, and avoiding ill-placed alloy puddles whenever possible. Put some environmental pep in your step with today’s Groupon: for $15, you get a pair of flip-flops from Feelgoodz (a $30 value, including standard ground shipping within the contiguous U.S.).

Constructed with all-natural rubber from the yang para latex tree, Feelgoodz flip-flops reflect a commitment to sustainable comfort that allows both feet and Mother Nature to breathe more easily. The company’s laid-back philosophy shines through in flip-flop designs made for everyday relaxation, but the laissez-faire attitude stops when it comes to a business model that emphasizes eco-friendly practices from extraction to disposal. Simplicity sets the tone for men’s and women’s flops such as the Moonlight and Ash, both emblematic of Feelgoodz’s signature two-color palette. Flops are compressed with high heat to achieve a level of comfort that graduates from cotton candy to kitten fur as they stretch to conform to feet over time. After countless beachside strolls and urban meanderings, flops can be returned to Feelgoodz via the unFlop recycling initiative, which is designed to cut up and repurpose old flops as bedding in compost bins.

After brief careers at a record shop and hot-dog stand, Feelgoodz founder Kyle Berner traveled to Thailand in an effort to satiate his existential thirst for meaning and open-toed footwear. Inspired by the local culture and population, Kyle built a business to enact positive social change and promote foot-smacking symphonies across the world. Years later, the Certified B Corporation carries on this vision by donating a portion of all 2011 sales to Pencils of Promise, an organization focused on building educational infrastructure in the developing world.
