New to barefoot shoes, start here by looking at why you should consider barefoot shoes in the first place!

Purpose and Versatility 🦶

Do you crave an adventure-ready sandal that can handle any terrain and weather condition? Perhaps it's time to consider the Oso Flaco Winged Edition and the Circadian Adventure sandals. While both of these minimalist options are popular among trail runners, there's more to them than just pounding the dirt. Let's dive into their purpose and versatility.

Starting with the Oso Flaco Winged Edition by Luna Sandals, this lightweight and high-performance sandal excels in outdoor activities like trail running, hiking, and river crossings. Its Vibram Megagrip studded tread ensures a solid grip on varied terrain, making it an adventurer's best friend. However, it's important to note that some users find the Oso Flaco more comfortable for running than for walking or hiking, and its appearance may not be everyone's cup of tea. Still, its focus is on providing the best in class performance for those big adventures.

On the other hand, the Circadian Adventure by Earth Runners is a versatile sandal that's equally adept in both urban and outdoor environments. The minimal aggressive sole and Earth-Grip footbed offer excellent traction in all weather, making it well-suited for long day hikes, strolls around town, and even as a comfortable camp shoe. With the Circadian Adventure, you'll find a balance between performance and aesthetics, fitting into a variety of settings while still performing well on the trails. Breaking in these sandals can take some time, and the cotton canvas footbed may require more frequent cleaning 🧼.

So, which of these sandals best suits your adventurous spirit? Are you looking for a high-performance trailblazer? Or do you prefer a more versatile and aesthetically pleasing option? Both the Oso Flaco Winged Edition and the Circadian Adventure have their strengths.

Design 😍

Let's dive into the design aspects of these two adventure-ready barefoot sandals. Starting with the upper materials, both sandals focus on delivering breathability, flexibility, and durability for outdoor adventures.

The Oso Flaco features performance laces and a secure wing design,

while the Circadian Adventure opts for Performance Laces to ensure a more secure fit.

Both sandals are vegan-friendly options, and the Circadian Adventure employs a cotton canvas footbed that offers extra grip in wet conditions.

So, just how "barefoot" are these models?

The Oso Flaco boasts a super lightweight build at 7.2 oz with a 7mm base and 4.5mm lugs on its Vibram Megagrip outsole.

In contrast, the Circadian Adventure features an aggressive sole design with Earth-Grip footbed, closely resembling a mild bare earth equivalent for that much-desired ground feel 👣.

The weight difference between the two models isn't significant, with the Circadian Adventure being slightly lighter. Nevertheless, both sandals are designed to be minimal and provide excellent ground feel for outdoor adventures.

Unique features? The Oso Flaco comes with the GEN3WINGS system for optimal performance and ease of use, while the Circadian Adventure is equipped with a conductive lacing system inspired by ancient huarache running sandals.

Both sandals have a rugged and functional look that's we think would look good anywhere.

Sizing and Fit Advice 📐

If you're not satisfied with how your sandals fit, Earth Runners offers a 30-day return/exchange policy as long as they're unworn, unwashed, and unaltered.

What does the barefoot shoe community has to say about these two sandals?

For the Oso Flaco Winged Edition, users commend its excellent traction on various terrains, lightweight design, and comfort during running.
