Honestly, the term "closed toe sandal" sounds like a bit of a contradiction. It’s a shoe that doesn't know if it wants to be a slipper, a clog, or a breezy summer staple. But if you’ve spent any time looking at footwear trends lately, you know that Birkenstock closed toe sandals—specifically the Boston clog and its various cousins—have moved from "gardening shoes for grandmas" to the absolute peak of high-fashion versatility.
They’re everywhere.
I’m talking about city streets, fashion weeks, and probably your local grocery store. It’s a weird phenomenon because, let’s be real, they aren't traditionally "pretty" shoes. They have a chunky, somewhat orthopedic silhouette that defies the sleek aesthetics we usually associate with luxury. Yet, here we are. The demand is so high that certain colorways, like the "Taupe" suede, are constantly sold out and reselling for double the retail price on sites like StockX.
People are obsessed.
The Anatomy of the Cork Footbed
The real magic of any Birkenstock, especially the closed-toe varieties, isn't actually the leather or the suede on top. It’s the footbed. It is a very specific blend of cork and natural latex that is designed to mimic the shape of a healthy foot in the sand. When you first slide your foot into a pair of Bostons or Londons, they might actually feel... bad. They’re stiff. They’re hard. The arch support feels aggressive, almost like you’re stepping on a tennis ball.
Give it two weeks.
That cork is reactive. Your body heat and weight slowly compress the material, molding it into a custom orthotic that is unique to your foot shape. It’s why you’ll see people clinging to ten-year-old pairs that look absolutely trashed; once they’re broken in, they are arguably the most comfortable shoes on the planet. This isn't just marketing fluff. The brand has been around since 1774, and the modern footbed was refined by Karl Birkenstock in the 1960s based on podiatric principles.
It’s science, basically.
The Boston: The Undisputed King
If we’re talking about Birkenstock closed toe sandals, the Boston is the elephant in the room. It’s the slip-on clog that defined the "cluttercore" and "granola-chic" aesthetics. What makes the Boston interesting is its seasonal flexibility. In the summer, you wear them barefoot with linen pants. In the winter? Throw on a pair of thick wool socks (the "Birks and socks" look is no longer a fashion crime, I promise) and you’ve got a year-round shoe.
The suede version is the softest, but if you want something that lasts through a literal apocalypse, go for the oiled leather. It develops a patina over time that looks better the more you beat it up.
The London: For When You Need a Back
Then there’s the London. Think of this as the Boston’s more professional, slightly more "adult" sibling. It’s a fully enclosed shoe, but it retains that low-profile, sandal-like feel. It’s a favorite among healthcare professionals and chefs because it offers the support of a Birkenstock but stays securely on the foot. It’s a bit more niche, but for people who find clogs too "floppy," the London is the perfect middle ground.
Why Do They Cost So Much?
You’re looking at anywhere from $120 to $190 for a pair of these. That’s a lot of money for what is essentially a cork slab with some cowhide on top. But here’s the thing: they are actually repairable.
Most modern shoes are "disposable." When the sole wears down on a pair of cheap sneakers, you throw them in the trash. Birkenstocks are different. A local cobbler can replace the EVA outsole. They can even replace the entire cork footbed while keeping your original, perfectly aged leather uppers. This longevity is a huge part of the value proposition. You aren't buying a shoe for a season; you're buying a piece of equipment that could last a decade if you treat it right.
Also, they’re still mostly made in Germany. In an era where almost all mass-market footwear is outsourced to high-volume factories with questionable quality control, Birkenstock has kept their manufacturing relatively localized. This allows them to maintain a level of consistency that’s rare nowadays.
The "Ugly" Shoe Trend and Cultural Shift
Why did these become "cool" all of a sudden? It’s a mix of things.
The pandemic definitely played a role. When everyone was stuck at home, we prioritized comfort over everything. Stiff dress shoes and high heels felt ridiculous. The Boston was the ultimate "house shoe" that you could also wear to grab coffee without looking like you were in your pajamas.
But there’s also the "ugly-cool" movement. Fashion has moved away from traditional glamour and toward "authentic" or "functional" looks. Brands like Stüssy and Dior have even collaborated with Birkenstock, putting their own spin on these closed-toe silhouettes. When Kim Jones puts a Birkenstock on a Dior runway, the conversation changes. It’s no longer just a shoe for hikers; it’s a design icon.
How to Not Get Ripped Off
Because of the hype, the market is flooded with fakes. If you see a pair of "authentic" Bostons on a random social media ad for $40, they are fake. Period.
- Check the Footbed: Real Birkenstocks have a suede lining on the footbed. It should feel soft, not like cheap plastic or rough synthetic microfiber.
- The Logo: The "Birkenstock" stamp on the side should be deep and crisp. Fakes often have shallow, blurry lettering.
- The Weight: Real cork is dense but surprisingly light. If the shoe feels heavy like solid rubber, it’s likely a knockoff.
- The Sole: The pattern on the bottom (the "bones" pattern) should be clean. On fakes, the edges of the pattern are often messy.
Choosing the Right Fit
This is where most people mess up. Birkenstocks come in two widths: Regular/Wide (the open footprint icon) and Medium/Narrow (the filled-in footprint icon).
Most men and many women actually need the Regular width. Your toes need room to spread out—that’s the whole point of the design. If your foot is sitting on the rim of the cork, they will be miserable. You want about 10mm of space in front of your toes and 5mm behind your heel. It feels "big" at first, but once you start walking, your foot moves. You need that clearance.
Maintenance and Longevity Tips
If you want your Birkenstock closed toe sandals to last long enough to become heirlooms, you have to do a little bit of work.
- Seal the Cork: When you first get them, the sides of the cork should look shiny. That’s the factory sealant. Once that shine wears off and the cork starts looking dry or flaky, apply a thin layer of "Cork Saver" or "Cork Sealer." It prevents the cork from drying out and cracking.
- Avoid High Heat: Never, ever leave them in a hot car or next to a radiator. High heat will shrink the EVA sole and can actually ruin the latex in the cork, making it brittle.
- Suede Care: If you have the suede Bostons, buy a suede brush. Give them a quick brush once a week to keep the nap from getting matted and gross.
- The Smell Factor: Since these are often worn without socks, they can get... funky. A simple trick is to wipe the footbed down with a damp cloth and a tiny bit of mild soap once a month. Let them air dry away from direct sunlight.
The Versatility Factor
I've seen people wear the Boston Clog with tailored trousers and a blazer, and somehow, it works. It grounds the outfit. It says, "I care about style, but I’m not trying too hard." It’s that effortless vibe that everyone is chasing.
On the other hand, you can wear them with sweatpants to walk the dog, and you don’t look like a total slob. They provide a structural element that flip-flops or cheap slides just don't have. They are the ultimate "middle ground" footwear.

Are They a Good Investment?
Look, at the end of the day, they're just shoes. But if you value your back and your feet, and you're tired of replacing cheap sandals every year, then yes. They are one of the few items in a modern wardrobe that actually lives up to the reputation. They aren't a fast-fashion trend that will be embarrassing in six months. They've been around for decades, and they'll be around for decades more.
Your Next Steps
If you're ready to pull the trigger on a pair, don't just order your usual sneaker size. Go to a local shop and actually try them on. Walk around. Feel the arch.
- Step 1: Measure your foot in millimeters to find your true Birkenstock size on their chart.
- Step 2: Decide on your "vibes"—Suede for comfort/fashion, Oiled Leather for durability, or the EVA version if you want something waterproof for the beach.
- Step 3: Commit to the break-in period. Wear them for 30 minutes a day around the house before taking them on a long walk.
- Step 4: Buy some cork sealer immediately. It's $10 and will save you $150 in the long run.
The break-in might be annoying, but once you cross that threshold, you'll understand why people are so cultish about them. Your feet will thank you.
