You've seen them everywhere. From the local gym locker room to the front row of high-fashion runways in Milan, slide sandals have basically taken over the world. But if you stop and think about it, they’re incredibly simple. It’s just a sole and a single strap. That’s it. No laces, no buckles, no heel straps to fiddle with while you’re rushing out the door.
So, what are slide sandals exactly, and why did they become a multi-billion dollar cultural phenomenon?
Honestly, the "slide" is defined by what it lacks. It’s an open-toed, backless shoe that you—clue’s in the name—slide your foot into. Unlike flip-flops, there’s no y-shaped thong to irritate the space between your toes. Unlike Birkenstocks (at least the classic Arizona model), there usually isn't a complex system of adjustable leather straps. It is the ultimate expression of "I just need to put something on my feet right now."
The Gritty History of the Locker Room Staple
It’s a mistake to think these are a new invention. People have been wearing versions of slides for thousands of years. Ancient Egyptians had them. The Romans had versions. But the slide sandals we recognize today—the rubberized, sporty ones—really found their footing in the 1960s and 70s.
Adidas is the big name here. Legend has it that the German football team wanted a shoe they could wear in the showers to protect them from the literal "funk" of communal locker rooms. They needed something that could get wet, dry fast, and wouldn’t slip on soapy tiles. In 1972, the Adidas Adilette was born. It featured that iconic three-stripe bandage across the top and a contoured footbed. It wasn't fashion. It was hygiene.
For decades, that’s where they stayed. They were for athletes. You wore them after soccer practice or while walking to the pool. If you wore them with socks in public back in 1995, you were basically asking to be roasted by your friends.
Fast forward to the 2010s, and everything changed. High fashion brands like Céline and Givenchy started putting "ugly" shoes on the runway. Suddenly, the "pool slide" was being made of Italian leather and mink fur. Then came the "normcore" movement, where looking like you didn't care about fashion became the ultimate fashion statement.
Why Your Feet Might Actually Love (or Hate) Them
From a biomechanical perspective, slide sandals are a mixed bag. Podiatrists like those at the American Podiatric Medical Association (APMA) often point out that not all slides are created equal.

If you buy a $5 pair of foam slides from a gas station, you’re basically walking on a flat piece of packing material. Your foot has to "grip" the shoe with your toes to keep it from flying off. This can lead to tendonitis or plantar fasciitis if you’re trekking miles in them.
However, the modern "recovery slide" is a different beast entirely. Brands like OOFOS or Hoka use proprietary foams—like OOfoam™—that claim to absorb 37% more impact than traditional footwear. They have high arches. They have rockered soles. For people with chronic foot pain or athletes who just finished a marathon, these aren't just shoes; they're medical equipment.
It’s weird to think that the same silhouette worn by a hungover college student to a 7-Eleven is also being recommended by orthopedic surgeons.
The Anatomy of a Slide
Let’s break down what actually makes a shoe a slide. If you’re shopping, you’ll notice a few specific variations:
The Bandage Slide: This is the classic. A single wide strap (the bandage) goes over the midfoot. These are usually the most secure because the strap covers a lot of surface area.
The Double Strap: Often confused with traditional sandals, these have two parallel straps. They look a bit more "dressy" but still maintain the backless slide entry.
The Platform Slide: Huge in the 90s and back again now. These add 2-3 inches of height. They’re heavy. They’re a bit of a trip hazard. But they look cool with wide-leg trousers.

The Recovery Slide: These look "chunky." They are often made of injection-molded EVA foam. They look a bit like a marshmallow and feel like one, too.
Beyond the Gym: How to Actually Style Them
There was a time when wearing slide sandals with a suit would get you kicked out of most offices. That time is gone. In a post-2020 world where "business casual" has basically dissolved into "please just wear pants," slides have found a niche in semi-formal wear.
If you want to pull this off without looking like you’re heading to the communal showers, material is everything. Look for:
- Full-grain leather straps.
- Suede footbeds (though these are a nightmare if they get wet).
- Neutral colors like tobacco, olive, or slate.
Pairing leather slides with linen pants is a classic Mediterranean look that works for dinner. On the flip side, the "socks and slides" look has been fully reclaimed by Gen Z. It’s no longer a fashion faux pas; it’s a deliberate choice. It’s about comfort. It’s about a certain "I’m too busy being creative to lace up my boots" vibe.
The Sustainability Problem
We have to talk about the plastic. Most mass-market slide sandals are made from synthetic polymers like Polyurethane (PU) or Ethylene Vinyl Acetate (EVA). These are essentially plastics.
When you buy a pair of $10 plastic shoes, they eventually end up in a landfill where they’ll stay for hundreds of years. Because they are often molded from a single piece of material, they aren't easy to recycle.
Thankfully, the industry is shifting. Brands like Indosole are making slides with soles repurposed from old tires. Others are using bio-based EVA derived from sugarcane. If you're looking for a pair, checking for "Bloom foam" (which uses algae biomass) is a good way to ensure your footwear isn't just more permanent trash.

Common Misconceptions About Slides
People often think "slides" and "flip-flops" are interchangeable terms. They aren't. Flip-flops are defined by that toe post. If you have sensory issues and hate things between your toes, flip-flops are a nightmare. Slides are the solution.
Another myth is that slides are "bad for your back." This is only true if they are flat and flimsy. A slide with a contoured footbed can actually provide better support than a pair of worn-out sneakers with collapsed arches.
And no, you don't have to be an athlete to wear them. While the "Adilette" started in the locker room, the modern slide is a lifestyle tool. It’s for the person who works from home and wants something better than a slipper but less formal than a loafer.
Choosing the Right Pair for Your Life
If you’re in the market for a new pair, don't just grab the first ones you see on a rack. Think about where you’re actually going to wear them.
For the beach or pool, stick to rubber or EVA. Leather will get ruined by salt water and sun. If you’re looking for an "everyday" shoe to wear to the grocery store or the movies, look for something with a cork or molded foam footbed. Your arches will thank you at the end of the day.
If you have wide feet, slides are a godsend. Most athletic brands make theirs with slightly adjustable Velcro straps hidden under the main bandage. This allows you to customize the fit in a way that most shoes just don't allow.
Practical Steps for Slide Longevity:
- Clean the Footbed: Use a damp cloth and mild soap. Sweat and skin oils build up on the footbed, making them slippery and, frankly, smelly.
- Avoid Direct Heat: If you leave EVA foam slides (like Yeezy Slides or Crocs) in a hot car or in direct 100-degree sunlight, they can actually shrink. I've seen a size 10 turn into a size 7 in one afternoon.
- Check the Tread: Because slides are often used near water, the tread wears down faster than on sneakers. Once the bottom is smooth, they become "banana peels." Toss them before you take a spill.
- Size Up: If you’re between sizes, always go up. A slide that's too small results in your heel hanging off the back, which looks messy and provides zero support.
Slide sandals are probably the most honest footwear we have. They don't pretend to be something they aren't. They are simple, functional, and—depending on your budget—either a $15 utility or a $500 fashion statement. In a world that's getting increasingly complicated, there's something genuinely nice about a shoe you just step into and go.
