Before comparing the different Luna Sandals models and telling you which sandal is thicker or which is best for the mountains, I'm going to tell you why Luna is not just another sandal.
Luna Sandals wasn't born in a marketing room with a whiteboard full of buzzwords. It was born from an obsession: the obsession of running again like humans ran before we were convinced that we needed a mattress under our feet.
If you've read Born to Run, Barefoot Ted will sound familiar to you. One of those colorful characters who seem exaggerated until you understand that the exaggerated one wasn't him. It was us.
Us, who have stuffed our feet into narrow, rigid, soft-everywhere shoes and then wonder why our bodies start complaining.
Barefoot Ted ended up in the Copper Canyon, Mexico, where he met Manuel Luna and the Tarahumara way of running with huaraches. From that spark came Luna Sandals: a simple, direct sandal designed for the foot to do its job again.
That's why this comparison isn't about "which sandal is prettier". It's about something else:
Choose Luna Venado 2.0 if you want the lightest and most direct Luna for asphalt.
It is the closest to "wearing the minimum". Good for walking, traveling, and running on clean surfaces. It's not the one I'd choose for loose rock.
Choose Luna Leadville Trail if you want a light sandal, but with more grip for trails.
It's a good entry point if you don't want to go to the Oso models, which are a step up in protection.
Choose Luna Mono Retro if you want a simple all-rounder, without side wings, with a good sole and clean feel.
I like it for those who want a classic multi-use Luna, without extra parts on the sides.
Choose Luna Mono Winged (Recommended) if you want the most balanced Luna.
For me, it is the easiest to recommend for almost everything. It has protection, fit, grip, and doesn't feel like a tank.
Choose Luna Mono Gordo Winged if you want comfort and more cushion without going to an aggressive trail sandal.
It has the most sole. More forgiving on the foot, but less defined in sensations. If you want to feel every pebble, this isn't the one.
Choose Luna Oso Flaco Retro if you want mountain use, grip, and an authentic feel.
It has that rare mix of serious sole and classic adjustment, but without looking like an open boot.
Choose Luna Oso Flaco Winged if you want technical mountain trails with more lateral security.
I think it's very good, but I wouldn't sell it as suitable for everyone. The wings help with the fit. But there are feet that don't get along with those wings.
Choose Luna Oso Winged if you want the maximum protection from Luna for the mountains.
Here you aren't coming to feel the ground. You're coming to feel the freedom a sandal gives you and to walk in the mountains without thinking about every step.

| Model | Sole / thickness | Approx. weight | Main use | What this means for you |

| Luna Venado 2.0 | 9 mm | 124 g | Asphalt | The lightest and most sensitive. A lot of ground feel. Little protection. |
| Luna Leadville Trail | 11 mm | 158 g | Mixed / light trail | More grip than Venado without losing lightness. |
| Luna Oso Flaco Retro | 11,5 mm | 204 g | Mountain | Serious sole, but still with a good reading of the terrain. |
| Luna Oso Flaco Winged | 11,5 mm | 204 g | Mountain | Powerful grip and Winged fit. |
| Luna Oso Winged | 17.5 mm approx. | 255 g approx. | Technical mountain | More protection. Less feel. More weight. |
| Luna Mono Retro | 15 mm | 167 g | All-terrain | Classic balance: medium protection and natural feel. |
| Luna Mono Winged | 15 mm | 167 g | All-terrain / running / walking | The most versatile. Good for those who want a single Luna. |
| Luna Mono Gordo Winged | 19 mm | 252 g approx. | Comfortable all-terrain | More sole, more comfort, less ground feel underfoot. |
This is about sandals, about that pleasure of feeling free toes. But it has a trap: since there is no upper to hug the foot like a shoe, everything depends on three key things:
In the Winged versions, the side wings help the strap stay more stable. You notice that, especially when walking fast, going downhill, or running.
But there are feet that get along well with the wings, and others that don't. If the inner side rubs or you have a very sensitive foot, you might need a few days to adapt.
This is key. Buy according to what you want to feel underneath:
Lunas are not flip-flops. They have to stay secured to the foot, but not strangling it. The strap must remain flush with the instep so the sole doesn't slide under it. For this, Luna has two adjustment systems: Retro and Winged.
It is cleaner and more huarache. There are fewer parts touching the foot, so the feeling is freer: foot, strap, and sole. Period.
The catch? It requires better adjustment. If you leave it loose, it slides. If you tighten it too much, it hurts. You have it on the Mono Retro and the Oso Flaco Retro.

Adds side wings. Offers more control, less lateral movement, and more safety if you walk fast, run, or go down irregular terrain.
The catch? If your foot doesn't fit well with those wings, you can feel them on the side or in the arch area. It doesn't always happen, but it does. You have it on the Mono Winged, Mono Gordo Winged, Oso Flaco Winged, and Oso Winged.

That's why when choosing your Luna Sandals I wouldn't choose just by aesthetics: if you want a simpler and freer Luna, look at the Retro; if you prefer more support and control, stick with the Winged.
If you walk on asphalt, promenade, city, or travel, you don't need an Oso. You have too much sandal. There, **Venado**, **Leadville**, or **Mono** make more sense:
Now, if you go on paths with loose rock, roots, downhills, and broken terrain, things change. There, the Oso Flaco starts to make sense, giving you grip and protection without moving you as far from the ground as the Oso Winged.
La Oso Winged is another story: it protects more, grips more, but also feels thicker and less refined underfoot, more focused on pure mountain.
This is like choosing a tool: you don't buy a machete to slice bread, and you don't buy a butter knife to go into the woods.
Here, Luna tends to play hard. It has its price, that must be said. But it's not a sandal to use for one summer and throw to the back of the closet smelling of swimming pool.
When you hold an Oso Flaco or an Oso Winged in your hand, you notice you're looking at a well-made sandal. The Vibram sole lasts a long time, the straps are soft but robust, and the package conveys that feeling of "you're going to have to abuse me a lot to finish me off".

However, durability doesn't fix a bad fit. A sandal can be indestructible and still not be right for your foot. That's what many people don't understand: don't buy just for durability, buy for fit.
If you ask me for just one recommendation, I would tell you that for most, the best option is the Luna Mono Winged. It is the most balanced: not the thinnest, nor the most protective, nor the lightest, but it scores very high in almost all categories.
And to finish, one last recommendation: don't buy the most technical one to look more mountaineer. Buy the one your foot is actually going to use. Because the best sandal is not the one that promises the most: it's the one you wear the most.
Spot on.
Health begins in your feet.
— Antonio Caballo
Measure your foot. Not the shoe you wear.
Luna sizes in US and is unisex, so the correct way is to look at the centimeter chart. If you are between two, don't guess. In huaraches, an ill-chosen size is very noticeable because there is no upper to correct the error.
Yes.
But if you are new to huaraches, give your foot time.
The strap between the toes and the webbing might need adaptation. If you're going to do many kilometers from day one, it's best to apply some petroleum jelly between the toes where the strap passes.
Yes, some models work very well:
But running with huaraches requires technique, adaptation, and fine adjustment. It's not just putting them on and going wild.
Oso Winged and Oso Flaco Winged.
The Oso protects more; the Oso Flaco leaves more ground feel.
If you are going to very technical terrain, choose Oso. If you want mountain trails but without losing so much reading underfoot, choose Oso Flaco.
Depends on your tolerance to thickness.
For many people, Mono Winged is the sweet spot.
If you want more protection underfoot, Mono Gordo Winged.
If you want lightness and ground feel, Leadville or Venado.
If you are not sure of the use: Mono Winged.
If you only go on city and asphalt: Venado 2.0.
If you want mountain trails: Oso Flaco Winged.
And if you want protection over sensation: Oso Winged.
