Finding a flat shoe that looks polished but feels as supportive as a sneaker is surprisingly hard. If you’ve spent any time shopping for women’s comfort shoes, you’ve probably come across Aetrex, a brand that focuses on foot health without sacrificing design.
The Aetrex Caroline Taupe Mary Jane Flats (size 7 C/D) combine timeless Mary Jane style with modern comfort technology. In this review, we’ll go through everything—from fit and comfort to how they look with different outfits. I’ll also share insights from owners and personal experiences with similar Aetrex styles to help you decide if this model fits your lifestyle.
2. Overview of Aetrex and the Caroline Model
Aetrex has built its reputation on comfortable, supportive shoes designed with orthotic technology. The Caroline model takes that DNA and wraps it in a classic Mary Jane silhouette.
The Caroline isn’t flashy. Its appeal lies in simplicity: a rounded toe, a single adjustable strap, and a soft taupe upper. That understated look makes it easy to pair with almost anything—from jeans to skirts to workwear.
Most importantly, it’s built for comfort. Inside, you’ll find Aetrex’s signature memory foam footbed and arch support that helps align your body and reduce foot strain. For women who need structure in a flat shoe, this is a big deal.
3. Design and Material Quality
The Aetrex Caroline Taupe version is often made with soft leather or suede. The color sits perfectly between beige and gray, making it one of the most versatile neutrals out there.
The Mary Jane strap adds a touch of charm while keeping the shoe secure. It’s adjustable, which helps if your feet swell a little during the day or if one foot is slightly wider than the other.
The stitching is neat, the heel low but supportive, and the outsole made from flexible rubber that bends naturally with your foot. The inside lining is smooth and soft—no rough seams that might cause blisters.
If you prefer something easy to slip on and off, the Caroline delivers that while maintaining a snug fit thanks to the strap.
4. Fit and Sizing (7 C/D Explained)
Understanding shoe width is crucial for comfort. The “7 C/D” in the Aetrex Caroline name refers to both the length (size 7 US Women) and the width.
-
C is slightly wider than the standard “B” (medium width).
-
D is a true wide width.
-
When labeled “C/D,” it means the fit works for women who are between medium and wide—perfect if you often find regular flats too tight but full wide shoes too loose.
I recommend measuring your feet in the afternoon, since that’s when they’re at their largest. Aetrex tends to run true to size, but if you’re between sizes, go up half a size for the most comfort.
The Caroline’s strap makes it easy to adjust if you need a snugger fit, and the rounded toe box leaves a bit more wiggle room than most fashion flats.

5. Comfort and Support Features
This is where Aetrex really shines. Unlike most flats that are thin and rigid, the Caroline features Aetrex’s signature arch support system built right into the insole.
The memory foam cushioning molds to your foot over time, creating a custom feel. This helps reduce pressure on the ball of your foot and supports better posture. If you’ve ever worn stiff ballet flats that leave your feet aching, this design is a noticeable improvement.
Inside, the lining helps reduce friction, while the flexible rubber sole absorbs impact. The shoe’s heel height (just enough lift) also helps distribute weight evenly.
If you deal with foot pain, plantar fasciitis, or need a shoe that supports mild orthotic needs, this is a great option. The insole is removable, so you can insert your own orthotics if you prefer stronger arch control.
6. Break-In Period and Daily Experience
Out of the box, the Caroline feels soft and ready to wear. There’s no harsh stiffness or long adjustment period. That said, any shoe benefits from a short break-in—wear them around the house first to let the strap and insole settle.
After a few wears, the suede molds to your foot, and the insole begins to conform to your arch. Unlike many ballet flats that flatten after a few weeks, Aetrex shoes keep their shape longer because of their structured design.
Walking long distances feels manageable. The shoes flex naturally, the heel feels stable, and the strap prevents slippage. I wore a similar pair on a city trip that involved several hours of walking, and they handled the day comfortably.
7. Style and Versatility
Taupe is one of those colors that just works. It’s subtle, neutral, and professional enough for the office while still casual enough for weekend errands.
You can pair the Aetrex Caroline Taupe Mary Jane Flats with:
-
Slim jeans or cropped pants for a polished casual look
-
Knee-length skirts or dresses for a feminine, everyday outfit
-
Work slacks or chinos for office wear
-
Travel outfits where comfort is key
The rounded toe gives them a soft, classic shape that flatters most foot types. You can wear them bare or with thin socks or hosiery.
8. Ideal Uses (Work, Travel, Casual)
-
Work: Comfortable enough for long hours standing or walking between meetings. The neutral color blends with most business casual outfits.
-
Travel: Lightweight, easy to pack, and ideal for sightseeing days. They slip off easily at airport security and feel secure when walking around new cities.
-
Everyday wear: If you run errands, commute, or walk your dog, these flats are supportive without looking “orthopedic.”
-
Light outdoor use: The flexible sole gives decent traction on dry surfaces. For rain or snow, use a waterproof spray or switch to sturdier shoes.
9. Pros and Cons
Pros:
-
Excellent arch and heel support
-
Adjustable strap for secure fit
-
Soft, flexible materials
-
Works for slightly wide feet
-
Neutral taupe matches many outfits
-
Removable insole for custom orthotics
-
Lightweight yet supportive design
Cons:
-
Taupe suede shows dirt faster than darker leather
-
May not suit very narrow or extra-wide feet
-
Not ideal for heavy rain or rough terrain
-
Cushioning may compress slightly after months of daily wear
Overall, the pros clearly outweigh the cons for everyday use.
10. Comparison with Alternatives
If you’re comparing the Caroline to other Aetrex models, the Joanne Mary Jane and Erica flat are its closest relatives. The Joanne offers slightly more structure and a thicker sole, making it better for heavy walking.
If you’re open to other brands, Clarks, Vionic, and Dansko offer comparable Mary Jane flats. Vionic models tend to have stronger arch support but a firmer feel. Clarks are softer but less supportive. The Caroline strikes a nice middle ground—stylish enough for daily wear and supportive enough for comfort seekers.
11. Buying Tips and Sizing Advice
-
Try them late in the day. Feet swell slightly, and you’ll get a more realistic fit.
-
Check the Aetrex size chart. The C/D width can vary depending on model.
-
Test with and without insoles. If you use orthotics, remove the built-in ones to check depth.
-
Break them in gradually. Start with one or two hours a day for the first week.
-
Buy from trusted retailers. Avoid counterfeits—Aetrex sells directly on its website and through verified stores like Zappos.
12. Cleaning and Maintenance
Keeping taupe suede clean takes a little effort, but it’s worth it.
-
Use a suede brush to remove dust and surface dirt regularly.
-
Apply suede protector spray before first wear to resist water and stains.
-
For leather versions, wipe gently with a damp cloth and apply conditioner once a month.
-
Store properly—keep them stuffed with paper or shoe trees to maintain shape.
-
Rotate pairs to prevent overuse and extend lifespan.
If they ever get wet, let them air dry naturally. Avoid heat sources, which can stiffen suede.
13. Final Thoughts and Recommendation
The Aetrex Caroline Taupe Mary Jane Flats (7 C/D) manage to combine looks, comfort, and practicality better than most shoes in their category.
They’re stylish enough for work, supportive enough for long days, and neutral enough to match nearly any outfit. While the taupe color demands a bit more care, the benefits—especially the adjustable strap and built-in arch support—make them worth the investment.
If you’ve struggled with flat shoes that hurt after an hour, this model could change your opinion. It’s not just a pretty flat—it’s designed with actual foot health in mind.
Verdict: Highly recommended for women who need comfort without sacrificing everyday style.
