If you’ve ever slipped on a pair of flat, open sandals that make a satisfying slapping sound with every step, you already know what a flip-flop is. But this simple shoe has one of the most fascinating stories in fashion history, and in 2026, it’s more stylish than ever.
A flip-flop is a light, open sandal with a flat sole and a Y-shaped strap that passes between the first and second toes. The name is widely believed to be anonomatopoeia because it literally describes the sound the shoe makes when you walk.
Who Invented Flip-Flops?
No single inventor created the flip-flop. This style of sandal evolved across many cultures over thousands of years. Evidence of thonged sandals traces back to ancient Egypt as far as 4,000 BC, with versions also seen in ancient Greece, Rome, China, Japan, and India, each made from locally available materials like papyrus, rice straw, wood, and rawhide.
The modern flip-flop caught on in the United States after World War II, when soldiers brought back Japanese zōri sandals. By the 1960s, they were firmly tied to California beach culture. In 1962, Brazilian brand Havaianas launched its iconic rubber version and now produces over 200 million pairs a year.
When Is National Flip-Flop Day?
National Flip-Flop Day falls on the third Friday in June after Memorial Day each year. In 2026, that’s June 19th. The day was created in 2007 by Tropical Smoothie Café to celebrate their 10th anniversary and raise money for Camp Sunshine, a free retreat for children with life-threatening illnesses in Casco, Maine.
Customers who visit participating cafés wearing flip-flops get a free Jetty Punch Smoothie, with proceeds going to the charity. Since 2007, over $3.7 million has been raised for Camp Sunshine through this celebration.
Are Flip-Flops in Style 2026?
Yes, very much so. In 2026, custom flip flops have officially become the ‘cool girl’ sandal of summer, appearing on runways. The dominant trend leans toward refined, minimal styles that think sleek leather, square toes, metallic finishes, and platform soles.
Y2K-inspired jelly flip-flops are also back, alongside kitten-heel and wedge versions that take this casual shoe into smarter, occasion-worthy territory. Whether you’re pairing them with denim shorts, a maxi dress, or a tailored summer outfit, there’s a trend for every style this season.
How to Decorate Flip-Flops?
Decorating flip-flops is one of the easiest summer DIY projects you can do. Here are five fun ways to make yours stand out:
- Wrap the straps with ribbon, yarn, or thin fabric strips. Overlap as you go and secure each end with a dab of waterproof craft glue or a few stitches.
- Glue on gems or rhinestones using a strong adhesive like E-6000 or UV-cure shoe glue. Flat-backed rhinestones, beads, and pearls all work great on rubber straps.
- Add a scarf or fabric by threading a thin scarf or strip of silk through the toe post and wrapping it around the straps for a boho, Grecian look.
- Paint the sole with acrylic craft paint or fabric paint. Draw patterns, initials, or geometric shapes directly on the footbed. Let it dry fully before wearing.
- Attach charms or pendants to the toe post using a small jump ring. This is a super quick way to add personality with no glue or tools needed.
How to Clean Flip-Flops?
Custom Printed Flip Flops pick up sand, bacteria, and sweat fast. Here’s how to keep them fresh based on the material:
- Rubber or foam: Soak in warm soapy water for 15 -20 minutes, scrub with an old toothbrush, rinse, and air-dry. Avoid direct sunlight, as it can warp the material.
- Machine-washable pairs: Place in a mesh laundry bag, run on a delicate cold cycle with a small amount of detergent and a cup of white vinegar. Air-dry only, no dryer.
- Leather flip-flops: Use a damp cloth and leather-safe cleaner. Never soak them. For dried stains, dab with white vinegar on a cloth and pat dry.
- Baking soda treatment: Sprinkle baking soda on the footbed, let sit for 5 – 10 minutes, then scrub and rinse. Great for both cleaning and deodorizing.
- After cleaning: Always air-dry completely in a shaded, well-ventilated spot before wearing again to prevent mold and odor.
