It’s not easy to find eco-friendly products that are also fashionable and affordable. Enter Simple Shoes. This spring, they introduced Flippees, the first flip-flops on the market with biodegradable soles. Flippees come in a variety of colors for both men and women at only $30 a pop.

Earlier this summer I ordered their Eco-Certified Nubuck Flippees in pink and black. My sandals arrived in a biodegradable bag with a biodegradable hanger, and the foot form inserts were made of post consumer recycled paper.

I was immediately impressed with the super-comfortable, egg-crate inspired footbed, and I decided to break in my new pair at Disneyland. This was a risky move; most new flip-flops chafe the skin between the toes and cause blisters. But I experienced no discomfort as I ran around the theme park and stood in long lines. The shoes also provided good traction.

I also felt good on the inside. Simple strives for 100 percent sustainability. As their motto goes, “HOW we make our shoes is just as important as WHY we make them.” Simple are vegan-friendly; they do not use animal products or even animal byproducts. What’s more, they use water-based (not petroleum-based) glue to hold the shoe together, and the soles are made of recycled and natural rubber that biodegrade after 20 years. Nothing’s perfect, though; if you’re concerned about ethical production, they are made in China.

Overall, I was extremely pleased with the Flippees and would strongly recommend them.
