The History Behind Boston Clog Mules & Why They Became Popular
Boston clog mules are having a moment—but their story goes back decades. From German craftsmanship to Gen-Z virality, here’s how this practical comfort shoe became a fashion icon.
🛠 Origins: Birkenstock & The Birth of the Boston
- The Boston clog was launched in 1979 by German brand Birkenstock. (PRM)
- Birkenstock itself goes way back (established in the 18th century), but its signature contoured cork footbed (introduced in the 1890s) laid the foundation for all its future designs. (PRM)
- The Boston was designed as a closed-toe alternative to the sandal line, made for cooler weather or indoor wear when open sandals weren’t practical. (PRM)
👟 Key Features That Set Boston Clogs Apart
- Anatomically shaped footbed made from cork & latex blend: molds to wearers’ feet over time, offering strong arch support (Footwear Plus Magazine)
- Simple adjustable strap with a buckle to secure the shoe, offering some degree of fit customization. (Her Campus)
- Durable materials: leather or suede uppers, often with variations like fleece-lined interiors for colder weather. (FOX 5 New York)
📚 Early Popularity: Comfort, Subculture & Practical Use
- In the 1980s & 1990s, the Boston found popularity among college students, “granola” lifestyle enthusiasts, and people embracing function over flashy fashion. Its reputation was built on comfort first. (British Vogue)
- Because Birkenstock was initially among hippie / counterculture circles, the Boston was seen more as a “comfort staple” rather than a style piece. (Business Insider)
🔄 Resurgence: How Boston Clog Mules Became Fashionable Again
Several threads contributed to their revival:
-
Comfort + Lifestyle Shifts
The pandemic shifted many toward comfort-first dressing — people spent more time at home, in cozy clothes, seeking shoes that are easy to slip on yet supportive. Boston clogs, including fleece or shearling lined versions, matched that need. (ELLE) -
Social Media & Virality
Platforms like TikTok and Instagram amplified Boston clogs’ popularity. For example, the hashtag #BirkenstockBoston gathered millions of views. Influencers and celebrities have been spotted wearing them, giving them status beyond just being cozy. (Her Campus) -
Designer Collaborations & Scarcity
Birkenstock has collaborated with high-end designers (Rick Owens, Manolo Blahnik, etc.) and launched limited colorways or special editions which made the Boston more desirable as a fashion icon. (ELLE) -
“Ugly Shoe” / Normcore / Comfort Aesthetic Trends
The trend toward “ugly-chic,” practical footwear, and mixing comfort with fashion meant Boston clogs were perfect: slightly unusual shape + maximum comfort = trendy. (King Stone Brothers and Co.)
🌍 Boston Clogs vs. Boston Mules: What's the Difference?
- “Clog” vs “Mule”: The Boston clog has a closed toe and usually a strap; the mule version tends to have no back heel support. Some fashion-style variations combine the Boston clog upper with a mule back (open heel), giving you “Boston mule.”
- Versatility: You can wear Boston clogs as nearly-mules by leaving heel strap loose, wearing with socks, etc. They functionally cross over depending on style and version.
👢 Why Boston Clog Mules Are Especially Popular Now (2025)
- They blend indoor/outdoor flexibility — part slipper, part shoe. So people love them for that hybrid comfort. (Her Campus)
- They work year-round: suede or fleece lines in colder months, and leather or unlined versions for mild or indoor use. (FOX 5 New York)
- Fashion cycles: Y2K revival, “early 2000s” nostalgia, “coastal grandma / cottagecore / comfort aesthetic” all feed into their increasing popularity. (ELLE)
- Price stability + durability: While they aren’t super cheap, many wearers report Boston clogs last many years, even a decade+, which makes them “value for money” in the comfort footwear space. (Reddit)
Celebrity Sightings: Boston Clog Mules in the Wild
- Gigi Hadid was spotted wearing Birkenstock Boston clogs with sweatpants and a casual tee, helping reframe them from “granola shoe” to stylish streetwear staple.
- Emma Watson wore Boston clogs during a Paris outing, pairing them with jeans and a barn jacket—showing how they fit into smart-casual, everyday style.
- Fashion media (Vogue, etc.) have featured the Boston clog as “the new Ugg slipper,” noting how celebrities like Kendall Jenner, Kaia Gerber, Sienna Miller, and Kristen Stewart adopt them across aesthetic styles.
- Celebs & street style features often show clogs styled with relaxed bottoms, layering, or socks — reinforcing their comfort + fashion crossover appeal.
🔎 Style Tips: How to Wear Boston Clog Mules
-
With socks: thick wool socks in winter, fun printed socks in more casual settings.
-
With wide-leg pants, cropped jeans, or midi skirts to show off the shape.
-
Use neutral colors (taupe, brown, black) for versatility; bold color or shearling models are statement pieces.

Indoor/outdoor crossover: some people wear them indoors/around the house like slippers and still out.
✅ Bottom Line
Boston clog mules (especially the Boston clog silhouette) went from niche comfort shoe to fashion staple thanks to their mix of practicality, comfort, and timely trends. With media visibility, collaborations, and lifestyle shifts leaning long toward comfort, there’s strong momentum sustaining them beyond just one season.
If you’re considering getting a pair, focus on fit (footbed type, width), lining for climate, and authentic sources (lots of fakes in resale). Once you try them, many say there’s no looking back.
