There are a lot of barefoot sandals out there.
A lot.
Some are good.
Others look like they were made from a chopping board and a washing line.
So here I’m going to walk you through Pies Sucios barefoot sandals, their differences and the kind of use each one really makes sense for.
This is not about telling you "this one is the best".
It’s about helping you understand which one fits you, your feet, your terrain and the way you’re actually going to use it.
And it made sense to start with Pies Sucios, because long before barefoot became trendy, this brand was already out there dealing with the rough stuff. Literally and figuratively.
Right now the range is very clear: Simna, Terra and Stone.

Quick verdict: which Pies Sucios sandal to choose
Each one belongs on different terrain. If you choose the wrong one, it’s not a disaster, but you will probably end up using a sandal that is too thin where you needed protection, or one that is too protective when what you really wanted was ground feel.
Simna: the thinnest and most direct option
Simna is the sandal for people who want to feel.
And when I say feel, I mean really feel.
The 6 mm version is very direct and makes more sense for someone already used to barefoot footwear or looking for a very minimal experience.
The 8 mm version keeps the same concept but gives you a little more margin when you walk longer or when the tarmac gets rougher.
Who is it for?
- City use and walks on pavement.
- Travelling light.
- Running if your technique is already there.
- Anyone who wants a sandal that almost disappears on the foot.
That said, if you come from heavily cushioned shoes, don’t go overboard on day one. Simna teaches a lot, but if you overdo it, you’ll feel it.
Terra: the most balanced option for almost everything
Terra has more sole than Simna, but it is still flexible.
It gives you more protection, but you still feel the terrain.
That means it works really well on pavement, tracks, easy trails and mixed terrain without making you focus on every single stone.
To me, it is the easiest one to recommend because most people are not looking for an extreme sandal. They want a sandal that genuinely works.
Something you can wear in summer, throw in a bag, use for walking, travelling and moving around without locking your foot up.
It has that extra bit of protection that gives you confidence, but it does not become a shoe pretending to be a sandal.
Put simply: Simna is purer; Terra is more practical. And very often, practical wins.
Stone: more protection for mountains and technical terrain
Stone is not made for grabbing bread or taking an easy walk on the seafront. This is about mountains, rock and loose ground.
Stone is built for more technical trails, rocky descents and routes where you do not want to suffer on every step.
It has more thickness, more lugs and more protection. And yes, that also means less direct ground feel than Simna or Terra.
This is important to understand: the most barefoot option is not always the best option.
On smooth pavement, a thin sole can be glorious. On a rocky downhill with tired calves, it can be a bad idea.
That is where Stone makes perfect sense. It is not the most sensitive or the lightest in feel, but when the terrain turns ugly, it gives you margin. And sometimes margin is exactly what lets you enjoy the route.
The three Pies Sucios models at a glance
Zip fit: the sandal should hold, not strangle
Pies Sucios has improved a lot here. In the past, many barefoot sandals had the same problem: either they felt loose and your foot moved around, or you tightened them so much they left marks across the instep.
With the Zip system, the idea is much simpler: set the fit once, leave the tension where you like it and then put them on and take them off without starting from scratch every day.
The key to fit:
not loose like a pool slide,
not tight like a ski boot.
It should hold the foot while still letting it move freely.
So, which one would I buy?
It depends on the use, of course. But if I had to simplify it a lot, I’d put it like this:
- Simna for city use, pavement, travel and a very barefoot feel.
- Terra for almost everything.
- Stone for more serious mountain use.
And if you are overthinking it, my opinion is pretty clear: Terra is the safest buy for most people.
It does not run out of protection as quickly as Simna when the terrain gets a bit rougher, and it is not as specific as Stone if you are mostly going to use it in town, on easy paths and through normal summer life.
Terra is the sandal you throw into the suitcase knowing it will actually get used. Not just for the photo. For real.
My final verdict
If you want a very pure and direct sandal, Simna. If you want the most balanced and easiest option to recommend, Terra. If you need more protection for mountains and technical terrain, Stone.
Frequently asked questions about Pies Sucios sandals
Yes, but do not look only at the terrain. Look at your feet too. If you come from conventional footwear and your feet feel weak or very sensitive, Stone can make sense because it gives you more margin. If your feet are already a bit adapted, Terra is usually the most balanced choice. And if you are already used to barefoot shoes and want maximum ground feel, then Simna is the one to look at.
Stone gives you the most protection. Then Terra. Then Simna. If what you want is more margin on rough terrain, that is the clear order.
Simna is the most direct. Then Terra. Then Stone. The more protection you add, the less direct ground feel you get.
Simna if you will mostly be moving around the city and want something very light. Terra if you want a more all-round sandal and you are not exactly sure what kind of ground you are going to find.
Terra works well on easy trails and tracks. Stone makes more sense if you are going to deal with rocks, loose terrain, descents or more technical routes where you want more protection under the foot.
