At one point or another, you may have heard that our feet can absorb a great deal of whatever is beneath them throughout our days. And while I’m not entirely sure how much of that is true, I think there’s a good metaphor here…

Our feet provide us with a foundation for our lives. They hold us up and allow us to move, to travel, to visit and play with our loved ones, to work, to experience all that life has to offer.

So because of all of that, wouldn’t we want to treat them well?

One easy way to treat your feet (and the planet) better this spring and summer is by choosing flip flops and sandals made from natural and non-toxic materials. In this article, we’ve rounded up our favorite brands for eco-friendly summer sandals that are good for your actual footprint and your carbon footprint!

What to Look for in Natural Sandals & Sustainable Flip Flops

Before we give you our favorite brands, let’s briefly talk about the types of materials we’re looking for in organic and non-toxic sandals:

Natural Rubber

Natural rubber is a renewable resource that comes from trees, whereas synthetic rubber is a petroleum byproduct that’s very similar to plastic. When possible, look for recycled and/or FSC certified natural rubber to ensure it’s sourced in a sustainable and ethical way. Several of the brands below work directly with rubber farmers to ensure they are paid fairly for their crop.

Of course, those who are allergic or sensitive to latex will want to choose a different material.


Cork is a great natural and eco-friendly material that’s used in a lot of shoes and sandals because of its ability to be durable, supportive, and naturally anti-bacterial. Recycled cork is even better!

Hemp & Organic Cotton

You’ll find that some of the brands below use organic cotton and hemp (mostly for the straps and upper parts of their sandals).

Hemp is one of our favorite sustainable fibers. It doesn’t require pesticides and herbicides to grow, it is not water-intensive, and it doesn’t strip the soil of the vital nutrients it will need to continue growing things in the future. It’s also a very durable, healthy, and breathable material that makes for a great sandal since it’s naturally anti-microbial!

Similarly, organic cotton is grown and harvested without the use of toxic synthetic pesticides and herbicides. Of course, it’s one of the more widely available types of organic fabrics, so you’ll see it in The Filtery’s guides quite a bit!

Vegetable-Tanned Leather

Conventional leather is tanned and processed using a lot of toxic chemicals and heavy metals, which can wreak havoc on the local communities where the leather is processed. Instead, go for vegetable-tanned leather which is tanned using tree bark and other plant materials.

Algae & Sugarcane Foams

There are quite a few newer sustainable materials making their way to the consumer market, and algae-based foam is one of those. This can be a better replacement for foams made from PVC and other plastic materials that are derived from fossil fuels.

The algae for these foams can either be grown in a man-made environment (which can help prevent the disruption of the ocean’s ecosystems) or it can be obtained from areas where there is actually too much natural algae growth that is causing harm to the ecosystem.

Some brands are also using a sugarcane-based EVA foam for their sandals. Although these plant-based EVA foams may not be perfect (they still require harsh chemicals to be processed and the sugarcane may not be sourced sustainably), they are at least better than traditional petroleum-based foams for now.

Plant-Based Leather

Other innovative materials to look for include pineapple and apple leather (which are great vegan leather alternatives), and other types of fabrics made from things like rice husks.

Non-Toxic Dyes

Lastly, you’ll want to look for brands that use dyes and colorants that are either natural and plant-based or safe synthetics.

Are Recycled Sandals and Flip Flops a Good Alternative?

There are plenty of brands that offer flip flops and sandals made from recycled materials like post-consumer plastic bottles, tire treads, fishing nets, old tires, and more. And while these options are certainly more sustainable than choosing virgin synthetics, one thing to be aware of is that materials like plastics, synthetic rubber, PVC, etc., can contain toxic chemicals like phthalates, petroleum derivatives, and other not-so-healthy things.

That’s why for this article, we’ve chosen brands that are trying to use mostly natural and/or naturally-derived materials.

Our Favorite Flip Flop & Sandal Brands Using Natural Materials

And now, without further ado, let’s get shopping. Here are our favorite non-toxic flip flops and sandals for this season:

Sea Sense

These plastic-free flip flops are made out of natural and sustainably-harvested rubber (which means they’re also vegan and biodegradable).

Available in men’s and women’s sizes, these flip flops are a great alternative to the conventional flip flops that you end up wearing all summer long. Throw them on to run errands, wear them to the beach or pool, or slide them on for a summer evening walk around the block.

If you’re looking for a more stylish luxury sandal, you should definitely check out D’Arçé. This brand makes its shoes using vegetable-tanned kangaroo leather, which is sourced locally. This obviously makes it an unappealing brand for vegans, however, D’Arçé makes an effort to limit how they get their kangaroo leather (it’s only obtained during controlled harvests to avoid overpopulation). They also have a policy of not wasting any of the leather, so they upcycle their scraps.

It’s also important to note that the leather is vegetable-tanned, which means it’s not processed using a bunch of toxic chemicals and heavy metals that conventional leather requires. Each pair of these sandals is handmade, too!
