How to measure your feet

1Step 1: Tape a piece of paper to the floor. Stand with your weight evenly balanced on both feet and place one foot on the paper.
2Step 2: With a pen or pencil pointed straight down, mark one line at the tip of your big toe and another at the outermost part of your heel. Repeat with the other foot.
3Step 3: Measure the distance between the two marks for each foot in inches or centimeters. It is common for one foot to be slightly larger.
4Step 4: Use the larger measurement to find your Hari Mari size. If your measurement falls between sizes, choose the next size up.

Frequently Asked Questions

What makes Hari Mari flip flops different than the rest of the market?

The difference is in the details. Our flip flops are crafted to be comfortable from the first step with no break-in periods, ever. We achieve this by using premium materials, arch supports, and our patented MemoryFoamToe™ post.

What is the MemoryFoamToe post?

Traditional sandals feature standard plastic or fabric toe posts that cause painful friction and blisters. Hari Mari holds an exclusive U.S. patent for our MemoryFoamToe™ post. This revolutionary memory foam toe post cradles the space between your toes, completely eliminating the painful break-in period common with other flip flops.

Are Hari Mari shoes safe to wear on boats, decks, or wet surfaces?

Yes! Our flip flop soles are made from molded rubber with plenty of texture, adding grip that may be lacking in some of your old favorites. We have several styles, including Clipper, Dunes, and Cape, that are fully waterproof—perfect for any day by the water.

Reviews Summary

Customers say these flip flops are extremely comfortable with good arch support and require no break-in time.

Another Awesome Pair
The best review is a purchase of the same footwear again. After about three years, my previous pair of Dunes started breaking down. I love them and wear them all year round.
Best thing to do was buy a new pair. And these don’t disappoint. The old ones are still in good shape; they’re just relegated to my backup pair now.
Keep crushing it, Hari Mari.

❤️ at first wear!
Several years ago I bought my first pair of women’s Dunes. I couldn’t believe how comfortable the footbed was as soon as I tried them on. The next summer I bought a pair for my husband and he, as well, couldn’t believe how comfortable they were. Finally, a few years later, it was time for replacements. I bought another pair of Dunes for myself, but my husband bought a cheap- o pair for himself while we were on vacation. At first he said they were fine and comfortable enough, but when he stepped onto a wet sidewalk and almost broke his ***, he was totally convinced… from now on, only Dunes will do! Not only are they comfortable, but the soles have a nice grip.
