​This post is Part 2 in my long-running shearling-lined Birkenstocks series and reflects my real-world experiences during the early evolution of fuzzy Birks—before today’s quality upgrades and expanded styles.  While my 2026 Shearling-Lined Birkenstocks guide covers everything current, this update documents what changed, what improved, and what I learned the hard way while wearing shearling Bostons and Arizonas year after year.

Christmas Day 2025: Three Generations of Shearling-Lined Birkenstocks

Shearling Lined Birkenstocks: A Cozy Update Since 2016

In 2016, I wrote a blog on shearling lined Birkenstocks.  Back then, shearling lined Birkenstocks was a new phenomenon and there were two major issues that I discovered with the shearling lining:

1. Exposed glue on the inseams
2. Slippery lining when wearing socks

From Skeptic to Believer: Why Shearling Lined Arizonas Work

At the time, I also could not put my head around a shearling lined Birkenstock sandal.  I felt that either you are hot (and need sandals) or cold (and need shearling).  A shearling lined Boston made perfect sense.  But, a shearling lined Arizona, not so much.

I am happy to report, three years later, that I now truly comprehend the pure luxury of a shearling lined Arizona.   Maybe it took the right color shearling lined Arizona to pique my interest and see the light.   In my opinion, a shearling lined Arizona gives one just the right amount of warmth and comfort on the foot, but allows breathing room for your tootsies.  And, you can wear them with socks, for extra warmth!

The Longevity of My Burgundy Shearling Bostons

I should mention that I did order a pair of burgundy shearling lined Bostons, in the fall of 2016, after I posted my initial blog on Birkenstock shearling lined shoes. That one pair of shearling lined Bostons has gotten some heavy wear over the last three years.  While I did find the shearling slippery right out of the box, they become less slippery as they broke in.​

A Decade Later: Shearling-Lined Birkenstocks Still Reign Supreme for Warmth, Comfort & Style in 2025

The shearling-lined Birkenstocks shown above are still going strong in 2025—proof that quality and comfort never go out of style. They even make an appearance in my latest video, released alongside Shearling-Lined Birkenstocks: Part 3.

After nearly a decade of testing, reviewing, and obsessing over fuzzy footbeds, I’ve learned there’s an art to finding the perfect pair of shearling-lined Birkenstocks. From my first cozy Bostons to my ever-growing collection of Arizonas, Green Suedes, and Uppsalas, I’ve explored every level of warmth, comfort, and style these fuzzy wonders offer.

No Zermatts here—they’re still not my thing—but you’ll see exactly how each shearling style stacks up for warmth, cushion, and support.

Why I Choose Shearling-Lined Birkenstocks Over UGGs for Everyday Comfort and Support

I am a sucker for shearling.  I love the coziness of my UGGs, but hate their lack of support.  After a few hours in UGGs, my feet hurt.  Unfortunately, Birkenstock insoles do not work in my UGGs.  Believe me, I have tried.  So, I usually only wear my UGGs when I am sitting on the couch.  Whereas I always wear my Birkenstock Bostons doing chores, walking the kids to school, or running errands.

I recently noticed that my Burgundy Bostons seemed a bit worn out.  The shearling mattes down over time and leaves grooves of exposed cork footbed where your toes and heels rub most in the shoe.  It is not a big deal if you are wearing socks.  But, it is extremely noticeable if you slip your foot into the shoe barefoot.

Falling in Love with Navy Shearling Arizonas

When it came time for a new pair of shearling lined Birkenstocks, I purchased the Navy Arizonas and immediately fell in love with the shearling.   So much so, that I frequented the Birkenstock webpage, waiting for Birkenstock to release the green shearling lined Boston in my size.  Thanks to the back in stock notifications, I snagged a pair the moment they were available.

A game changer! My Navy shearling lined Arizonas with socks — warm, plush, and perfect for chilly mornings. My friend in her Big Buckle Madrids.

Green Shearling Lined Bostons: Worth the Wait

With my new shearling lined Birkenstocks, I did not have any issues with exposed glue seams. The shearling also seems more plush than previous releases.  Even with the extra plushness of the shearling, I still found the shearling slippery the first few wears, but that issue tends to resolve itself quickly.  It is such a pleasure not to have to deal with any quality control issues regarding the shearling or exposed glue.

After waiting for a restock, I finally snagged these Green shearling lined Bostons — worth every moment!

The Narrow Width Problem with Shearling Styles

While the quality of shearling lined Birkenstocks has been upgraded, there is one small problem that I think Birkenstock needs to take into consideration…..regular width options.  When you take a narrow width Birkenstock and line it with shearling, you take away a lot of valuable real estate on that footbed!

I fell in love with the dove gray color this season, but it was only released in narrow width in the US.  Why?  It is SO LAME that Birkenstock does this.   I don’t need to go into detail about my feelings on narrow width Birkenstocks.  If you have been reading my blog, you already know my stance on that matter.  If you are a new reader, you can learn more by reading Narrow Minded US.  

Custom Solutions: Stretching Narrow Shearling Birkenstock

When I ordered the dove gray Bostons, I could not even fit my foot into the narrow width shoe.  It felt two sizes too small!!  Be sure to get properly fitted before buying shearling lined Birkenstocks.  Learn how to get the right size in my article Stepping Into Your First Pair.  Some people who wear narrow width sandals, may need a regular width, if the Birk is lined with shearling, and some people may need to size up.  I personally take my normal size and now I know that I cannot wear a narrow Birk with shearling...unless I call Michelangelo at Custom Made Birkenstocks, and have him stretch out a pair for me!  You can call him too and ask him to stretch out your Birkenstocks!  It works.

My Dove Gray shearling Bostons were too narrow, so Michelangelo at Custom Made Birkenstocks stretched them to a perfect fit.

Are Shearling Lined Birkenstocks Worth the Price?

I realize that shearling lined Birkenstocks are outrageously expensive.   This is part of the reason that I have decided to write an updated blog on the subject.  I want everyone to know that shearling lined Birkenstocks are high-quality, well worth the money, and last for a long time.  Custom Made Birkenstocks now has shearling lined footbeds and can recraft an older pair of Birks with a fresh, new shearling lined footbed!  Imagine taking an older pair of your favorite Birks and recrafting them with a shearling liner!!  The possibilities are endless.
My Everyday Winter Staple: Shearling Lined Bostons


Even though the price of the shearling lined Birkenstocks might seem astronomical, if you are like me, they may be the one pair of Birks that you wear the most!  During the spring and summer, I rarely wear the same Birkenstocks twice.   But come fall and winter, I pretty much wear my shearling lined Bostons every single day!  When it is hella cold outside, my burgundy Bostons are on my feet from the moment I wake up, to the moment I go to bed.  I have certainly gotten my bang for the buck with this one pair!

Final Thoughts: Why Every Birkenstock Fan Should Try Shearling

Would I recommend you give shearling lined Birkenstocks a try? Absolutely!  If you like UGGs and love Birkenstocks, then shearling lined Birks are the perfect shoe for you.  It’s a win win.
