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.
Patented hugflex™ + barecork™ · Handcrafted in Portugal · Machine washable · 100% Vegan ·  30-day Feel Free guarantee
Free Shipping

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.

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.

Engineered for Different Rides

Mullen

the barefoot hug. Our most minimal slide. The shortest hugflex™ strap in our collection for a free, uninhibited feel. Classic slide width, our own unique interpretation.

Shaw

the secure hug. Shaw's strap is about 20% longer than the Mullen, wrapping more of the foot for a more sophisticated ride. Supportive enough for a 20,000-step day, effortless enough to still be a slide.

Reviews

These slides are stunning. They

"These slides are stunning. They are level 10 comfortable, all while being chic and versatile. I was tired of wearing flip-flops day to day, and these are the perfect upgrade. I had an issue with a past purchase, and Message customer service went above and beyond to make it right. I am impressed with both the quality of the shoes and the quality of service!"

Jenna M. (5/5)

Where do I begin to

"Where do I begin to thank you for designing these slides?! Right out of the package, they feel like they were made just for me. The footbed is divine; the stretchy strap is a gently hug; no flopping around or need for me to focus on keeping them on my feet. Truly a dream come true and I'm already ordering another pair."

Cathy G. (5/5)

My foot is a little

"My foot is a little wide for them, so they are a bit snug. It said to size down if you’re in between sizes, which in my case I shouldn’t have with a wide foot. It has an arch support I don’t need (I feel the bump out), so I think I’ll have to break them in. They will be house shoes for now. Definitely a nice design and very earthy, which i like. I’m an 8 1/2 and i got a 38."

Wow, I just opened my

"Wow, I just opened my package and they're super comfortable!!! Seen to have a firm support. I'm excited to switch up my sandals!"

Yasmine D. (5/5)

Received my shoes today. They

"Received my shoes today. They seem like they will be very comfortable and do seem true to size. I love the way it hugs my foot and has good arch support. The only thing I’m a little disappointed with is the color. I ordered the stone ripple. In the pictures online they look more of a tan/light brown color. I’m not sure if I was sent the wrong color or not, but in person they lean to more of a light army greenish color. Still a nice color…but for me, just not what I was wanting or expected them to be. I still haven’t decided if I will keep them or not."

Brandy R. (4/5)

Love them! Exactly what I

"Love them! Exactly what I was looking for and very comfortable. Worth the wait. Have not washed them yet but excited for that feature. They can get wet and seem to dry quickly. Runs true to size. I also had a great customer experience with Ivan when I didn’t realize they were on back order. Super responsive and friendly."

Heidi W. (5/5)

I actually love them. I

"I actually love them. I have always used Birkenstocks and now found my new favorite sandal. I like that I can actually wash them. At first the slapping sound I thought was going to be a problem but you actually don't notice it once you walk awhile in them. They are so comfortable and light. I am actually thinking of ordering another pair soon."

Elisabeth D. (5/5)

Great looking and seem comfortable but sizing is inconsistent!!!

"I was so excited to receive these after pre-ordering them, they are very good looking! They arrived a day before a trip and I was thrilled to be able to wear them, however, SIZING IS INCONSISTENT. I hope someone else can crack the code on the sizing of the Mullen and Shaw slides. I normally wear an 8 and according to the size chart I should wear a 38. 38 in the Mullen slide is too big, I couldn't return them since they were worn. Message customer service suggested I try the Shaw in a 37 (I found them on another site) and those are too small! Super frustrating!!! I'll stick to my Birkenstocks for now, but I had high hopes for these slides but am very disappointed!"

Want to say excited because

"Want to say excited because it took nearly 2 months to receive… the color is olive toned not the stone/taupe I expected I am keeping only because it took so long and I am hoping the hype in comfort is worth it"

Teresa W. (5/5)

So comfortable. I wear them

"So comfortable. I wear them all day, they look great with everything. Definitely will be purchasing other colors. True to size."
