Black Mullen Slide

$150
The barefoot hug. Our most minimal, free-feeling slide. The Mullen is an ultra lightweight, springy, and uninhibited ride. It offers room for your toes to spread, and real support where it counts. Molds to your foot over time, and if it doesn't feel like yours within 30 days, we'll make it right.

barecork™ footbed.  

Crafted from upcycled wine cork, harvested from cork oak forests in Portugal every nine years without harming the tree. Water-safe, cork-on-cork construction molds to your foot, naturally absorbs impact, and provides subtle arch support without added weight. Cork is a natural material and may show minor separation or flaking with wear—this is normal and does not affect function or comfort.

hugflex™ upper. 

A patented compression stretch-knit that wraps the foot like a sock. It holds without pinching, flexes as you move, and never needs to be broken in. The Mullen's minimal strap keeps the ride light and free.

Natural rubber sole. 

Flexible, durable, grounded.

100% vegan. 

No animal materials. Get them wet; these are quick-drying materials. 

Handcrafted in Portugal. 

Handcrafted in small batches by 2nd- and 3rd-generation family-owned workshops outside Porto, all within forty minutes of one another. The cork is carbon-negative, and the production runs are small to keep waste at zero. Built to last, not to pile up.

If you are in between half sizes, size down. For instance, if you are a size 39.5, choose a size 39.

Fit

Our straps are designed to hold the foot snug but not tight, like a really good hug. We recommend pulling them on like socks, shimmying your toes to the top of the slide for a secure, comfy, strapped-in fit. Measurements below are based on a size 38.


MULLEN

Original, wear-everywhere silhouette, comfortably snug but with more spring in your step.

SHAW

Increased stability improves your every move and fits every foot just right, even narrow feet.

MESSAGE slides are 100% machine washable. Gentle cycle, cold water, air dry. The cork is water-safe, naturally antimicrobial and antifungal, they stay fresh however far you walk in them.

Reviews

These shoes are great, but

"These shoes are great, but this particular pair was the wrong size, so I had to return. I had purchased a different pair in the smaller size that ended up being perfect. I am going to give these a 5 star review more for the other pair and for the easy customer service. I'd say the shoes run a little bit large. They are really comfortable and the customer service was excellent."

— Siobhan F. (5/5)

I have not owned these

"I have not owned these or worn these enough yet to say much from experience, but from just putting them on they need no break in and are extremely comfortable. They are also built to last and feel as such."

— Roger B. (5/5)

Love right out of the

"Love right out of the package. I haven't a low instep and narrow foot. These actually are the most comfortable slides ever. I have many, i mean many birkenstocks and these are my new favorites. Already ordered a second pair. Can't wait for them to arrive."

— Sheryl S. (5/5)

As a devoted Birkenstock, where

"As a devoted Birkenstock, where I have been pleasantly surprised with my purchase these slides. As a seven-year-old woman I feel like my Birkenstocks just aren’t feminine they’re functional, but not feminine. I feel like the slides are feminine and they can be washed and that has me sold."

— Laurel F. (5/5)

Very comfy strap, doesn’t feel

"Very comfy strap, doesn’t feel like you have to break it in. Guessed right with my size. I ordered the same European size I wear in Birkenstocks and they fit perfectly. The cork is heavier and firmer than I thought it would be but excited to put some miles on these because they feel like they are going to hold up. They feel high quality. Worth the wait, just wish I got them at the beginning of summer and not the end."

— Kristin K. (5/5)

"I was very excited to receive the sandal after a 6-week wait. Walking in the house was very comfortable; however, when I went for a walk outside, the slapping sound was so loud I couldn’t ignore it. It sounded like I was wearing flip-flops, only MUCH louder because the footbed is cork, not rubber. By then I couldn’t return the shoe. Perhaps the problem would not occur with the Shaw, which has a wider strap across the top, but I am not going to chance purchasing another sandal that I will be unable to return."

— Jodie (2/5)

"The shoes are very comfortable. The problem is the elastic strap across the foot has enough give that the shoes make a loud thunk with every step. Every step the back pops back in to the heel and is loud. No matter how softly I try to walk. I do not wear them out of the house."

— Dana (3/5)

I walk a lot at

"I walk a lot at work, so I was really excited about the style of these shoes, but also that they were washable so I can keep them clean and wear them for seasons to come. My first pair didn't have the perfect fit, but the Message team was so responsive and helped me get the right pair, without any extra cost, which I greatly appreciated. I love my new slides, but the way the brand responded spoke volumes and really tipped my excitement in an even more positive direction."

— Sydney G. (5/5)

Just purchased the mullen slide

"Just purchased the mullen slide and love the cork bed feel. It isn't hot or sweaty for these warm summer days. Arch support is great and the band works well too as I have high arches."

— Susan A. (5/5)

So comfortable and stylish. I

"So comfortable and stylish. I am usually a 7. 5 in flats and 8 in tennis shoes/boots. The 38 fit perfectly! I have narrow feet and love the compression, as it feels secure and right amount of snug."

— Melissa W. (5/5)

Q&A

Are they good for high arches? I need good arch support. Will these work for me? Also is the cork hard or cushiony? I can’t wear Birkenstocks because they are too hard and hurt my feet.
Hi Melinda, Yes! The Mullen is actually our favorite for higher arches because of its shorter knit, which gives your foot a secure hug without feeling overly restrictive. Our cork footbed is supportive. The Mullen has a featherweight, springy & flexible ride, so it’s designed to move more naturally with your foot while still keeping you grounded.
