SL 03 Full Grain Chocolate Full Grain Leather
Frequently bought together.
Two straps crossed over the foot, and nothing else asked of you. The SL 03 holds through the crossover rather than a buckle, which keeps the top of the foot open and the shape flat. Light enough to travel with, structured enough to wear into town. For slow mornings and warm afternoons.
- An EVA sole, light enough to walk a city in.
- A ribbed outsole for grip on smooth ground.
- Crossed straps that hold the foot without a buckle, so the top of the foot stays open.
- No laces and no hardware, so you step in and go.
- Handmade in Portugal, in a family-run factory we have worked with for years. Designed in the Netherlands.
- A full-grain leather upper that marks, then settles.
- An onSteam® footbed that stays soft underfoot and moves moisture away.
- The ETQ signature square, pressed into the strap.
- A reusable travel bag comes in the box, for wherever the shoes go next.
- The white box is the shipping box, so there is no second carton to throw away.

Handmade in Portugal.
Cut from premium nappa, full grain and suede, then built on the last by makers who do little else. It takes years to master a shoe. We're still finding ways to make it better.
One box. Nothing wasted.
Every pair ships in a crisp white box built to be the shipping box too — no second carton, nothing thrown away. Inside, a reusable ETQ travel bag for wherever they go next. A detail you notice after you buy, not just before.
Endless comfort.
A structured silhouette on the outside. Inside, a memory-foam insole with airflow channels that move moisture with every step. The kind of shoe you forget you're wearing — and keep on long after you meant to.

Made in Europe
Kings of detail we are.
At ETQ we focus on the things even the eye can’t see, to build better. All shoes are designed in Amsterdam and crafted in Portugal. The family-owned atelier works with traditional methods. Together we are masters of precision engineering.
When it comes to materials, our bar is high. No shortcuts. ETQs premium suedes and leathers are smooth like butter and cherry-picked per shoe. Obsessive, yes. But: soon after wearing ETQ you will notice the quality difference.
The full package
Unboxing like never before
Your fresh pair arrives in style. Your shoes come in two all-purpose zip bags made from recycled PET bottles. Use them to store your ETQs, toiletries, pencils, and more. Just like your shoes, these bags are crafted to last.
We've always been fascinated by packaging. We designed it with efficiency and with the environment in mind. The modular packaging consists of long-lasting items created with recycled materials, while the shipping box is repurposed to serve as a shoebox as well.
Endless comfort
Time suits them
Beyond trends and flashy labels. Our style never changes. It evolves. Continuously.
Confident and comfortable, ETQ introduces the etiquette of artisan shoe crafting to today’s sneaker world. We blend traditional cobbler skills with the latest technology for comfort and suppleness. Your feet feel it, every step of the way.
While traditional sneakers are meant for sports, ETQ footwear is made for the city. That is why we use a solid and heavy cupped sole made from reinforced rubber to last in all conditions. Fit so smooth that you’ll want to keep them on. And you can.

Excellent design and high-quality leather
I'd been looking for this style of crossed sandals for a long time. They're very comfortable, yet elegant and delicate. I really liked that ETQ got the sizing recommendation just right. Made in Portugal with a Nordic design. Top-notch.
Flop
Size too small. The size was nowhere printed on the shoes, at the sole for example. The “Made in …” was nowhere printed, at the sole for example.
"Top quality, top comfort"
Beautiful leather, great finish—top-notch
Awesome
Great fabric, good fit, and comfortable to wear. I highly recommend them.
Not the value for the price I expected
I bought a pair of flip-flops for almost €100, but after wearing them for a week, nearly half the tread is gone. The sole is just too soft. I checked the link below the size chart to see which size I should order, but unfortunately, they were still too small. So the sizing guide isn’t accurate—if you decide to buy these, go up a size.
high quality
for day to day use in and around the house, not for long walks. Very comfy and well made, good quality material
Super
Very comfortable and quality is perfect.
Nice flip-flops
High-quality flip-flops that are extremely comfortable to walk in. Made of supple, soft suede with a flexible sole.

Neat, stylish flip-flops. Good quality. They run a size smaller, though.

Beautiful products that look sturdy and high-quality
Amazing quality
Products are always of high quality, great brand. I needed one size above sneaker size.
Nice flip-flops
A beautifully crafted slipper that's comfortable. Order one size larger than your usual shoe size.

Fast delivery
Top quality and fast delivery
Great quality and comfortable to wear
These are really comfortable and cute flip-flops; I would recommend getting a size larger than your usual size. Other than that, I'm satisfied with the customer service.
Good
Great quality. Unfortunately it was too small and i had to send it back. It has been weeks and the next size up is out of stock, so I can't get a new pair. Apart from that,all great.
Stylish, quality and comfort
Surprised bij the combination of 3 elements that make shoes an eyecatcher or not. My husband gets lots of compliments. Take one size bigger.
Awesome
Great fit, comfortable flip-flops
Runs small
It runs two sizes too small—too bad that isn't mentioned!
The perfect Slipper
These are really really nice. They look great, walk really softly and you can were them under anything. Also for a casual night out on the terrace. Very happy with them.
not as comfortable as the sneakers
these are not so comfortable as I am used to
High quality and elegant
Product presents itself very well and elegant. Size wise i wear a 43 and ordered a 43 which matched my foot.
Beautiful
Magnificent sandals
I dont’t usually like sandals, but when I saw these in the photo, I was intrigued and wanted to try them. I wasn’t wrong, they’re gorgeous, elegant, super comfortable and super soft. I’m very satisfied
Stylish, comfortable sandal.
These are really comfortable and smart sandal. Quick delivery as always from ETQ.
Highly recommended!
The suede slippers are surprisingly comfortable and soft to the touch. The finish looks neat and the material gives a luxurious look. They walk comfortably, even with longer wear, and combine easily with casual outfits. Good value for money and definitely recommended for daily wear.

How to measure
Let’s find your perfect fit. Place a sheet of paper on the floor against the wall and put your feet (with socks) on it, heels against the wall. Make sure you lean on your feet with full power when measuring. Now you simply draw a line at the end of the biggest foot. Measure the distance with a ruler and find the size that matches it: see size table. Are you in between sizes? In that case, we suggest taking the bigger size.
ETQ Footwear — Size Guide

Place a sheet of paper on the floor against a wall. Stand on it with your socks on, heels touching the wall.

Between sizes?
Choose the larger size. Feet naturally expand throughout the day, so measuring in the evening usually gives the most accurate result.
