Purpose and Versatility 🦶

Considering the range of activities and adventures you can enjoy in barefoot shoes, let's dive into the purpose and versatility of the Oso Flaco Winged Edition and the Middle Bear Winged Edition. Both are designed to serve different needs, so understanding which one suits your preferred activities is crucial.

The Oso Flaco is perfect for those who crave performance-focused minimalist footwear for BIG adventures. Its Vibram Megagrip studded tread offers incredible traction, making it ideal for tackling mountains, rivers, trails, and mud. In contrast, the Middle Bear provides a rugged trail sandal with ample grip and rock protection, making it suitable for anything from epic mountain adventures to mellow trail runs. The Middle Bear offers a thicker sole for extra cushioning, and the Oso Flaco offers more ground feel 😃.

While the Oso Flaco is primarily recommended for minimalist trail running, it may not be the best option for other activities. Users have reported it's less comfortable for walking or hiking and feels slightly less supportive when carrying a heavy load. On the other hand, the Middle Bear performs well on various terrains, including muddy or rocky trails, providing excellent grip and confidence while running 🏃‍♂️.

When it comes to versatility, the Middle Bear arguably offers more options for different activities. However, if you're seeking a more minimal, ground-feel-focused sandal for trail running, the Oso Flaco is your go-to choice. Ultimately, your preference for cushioning and ground-feel will guide your decision. Just remember to use proper sizing advice with Luna Sandals, as their sizing differs from other brands.

Design 😍

When it comes to design, these two barefoot sandals have some significant differences that cater to specific preferences and needs.

The Oso Flaco Winged Edition shines in its minimalist approach, with a lightweight construction of just 7.2 oz (single sandal, men's size 9). This sandal sports a 7mm base and 4.5mm lugs, providing just the right balance of ground feel and protection for those who crave performance-focused minimalism.

On the other hand, the Middle Bear Winged Edition is slightly heavier at 8.2 oz (single sandal, men's size 9.5) and boasts a thicker 9.4mm base and 4.5mm lugs. This extra thickness provides more cushioning and protection, making it a suitable choice for those who prefer a more luxurious feel underfoot during their adventures.

Both models use Vibram® Megagrip outsoles for exceptional traction, and MGT (Monkey Grip Technology) footbeds for added grip during any activity. These vegan-friendly sandals are made with durable, animal-free materials and are lovingly crafted in Vietnam. The Gen3Wings lacing system in both models ensures a secure fit with minimal hassle, allowing you to focus on enjoying your outdoor escapades with ease.

As for aesthetics, the Oso Flaco and Middle Bear both have their own unique looks, but we know that style is a personal choice. So, we won't dwell too much on that aspect. Instead, we encourage you to focus on the functionality and performance that these sandals offer, and to choose the right size for the perfect fit. After all, the most important thing is finding a design that meets your needs and keeps your feet happy and healthy.

Sizing and Fit Advice 📐

Getting the perfect fit is crucial for your barefoot shoe journey, so let's dive into the sizing advice for the Oso Flaco Winged Edition and the Middle Bear Winged Edition.

For both models, most men tend to size down 1/2 to a full size, while most women are true to size. It's essential to remember that with LUNAs, you want a close fit and not a lot of space around your foot. To assist you in finding the right size, Luna Sandals provides a size guide on their website, which includes a foot-sizing template for accurate sizing. We really do emphasize the importance of using this template, as Luna's sizing is different from other brands.

When it comes to adjusting the fit, some users reported it could be a bit challenging for the Oso Flaco Winged Edition, requiring trial-and-error to get it just right. The Middle Bear Winged Edition, on the other hand, received praise for its easy-to-adjust lacing system, allowing users to get the perfect tension.

We recommend trying on the sandals yourself if possible, as their unique fit and design may suit individual preferences differently. If you need further guidance on sizing and fitting, feel free to refer to our comprehensive barefoot shoe sizing guide.

Users of the OSO Flaco Winged Edition appreciated the excellent traction on various terrains and its lightweight feel. However, some found the lugs to be sharp and reported discomfort with the thin straps and fixed rubber elements on the sides of the foot.
