Purpose and Versatility 🦶

Let's talk about the adventures you can embark on with these two barefoot sandals. On one hand, we have the Oso Flaco Winged Edition designed for those demanding high-performance minimalist footwear for big adventures like mountains, rivers, trails, and mud. On the other foot, we've got the Forclaz Trek 500 offering an ultra-light and compact option for hikers wanting a reliable sandal during bivouacking phases. But which one will suit your adventurous feet the best? 🤔

The Oso Flaco is primarily designed for minimalist trail running, while the Forclaz Trek 500 has a focus on being a restful companion during bivouacking breaks. However, both sandals can be used for a variety of activities, albeit with different limitations. Some people find the Oso Flaco Winged more comfortable for running than for walking or hiking, and it might not provide enough support for heavy loads. On the other hand, the Trek 500 may be versatile for short walks, but its stiffer sole could be a challenge for long hikes or slippery terrains.

When it comes to water resistance, the Oso Flaco is made of waterproof, non-marking Vibram® Megagrip Outsole and a MGT (Monkey Grip Technology) footbed. The Trek 500 is also described as hydrophobic and suitable for taking a shower in mountain refuges. So, if you're planning to cross some streams or face the occasional shower, both sandals have got you covered, literally!

Design 😍

When it comes to the design of these barefoot sandals, materials, and overall barefoot feel are critical factors to consider. So, how do the Oso Flaco Winged Edition and the Forclaz Trek 500 compare?

Let's start with the uppers. The Oso Flaco Winged Edition utilizes soft and durable tubular performance laces with a secure wing design. This minimalist foot harnessing system offers optimal performance and ease of use. Plus, these sandals are vegan-friendly with no animal-derived materials.

The Forclaz Trek 500 sandals feature basic, hydrophobic straps, making them suitable for wet conditions like showers in mountain refuges and are also vegan-friendly.

Moving on to the soles, the Oso Flaco Winged Edition boasts a 7mm base with 4.5mm lugs made from Vibram® Megagrip for excellent traction on various terrains. This sandal is also incredibly lightweight at just 7.2 oz (single sandal, men's size 9). Conversely, the Forclaz Trek 500 has a slightly stiffer sole and a slight heel rise, providing more support but reducing ground feel compared to the Oso Flaco.

In terms of weight, the Forclaz Trek 500 is no slouch either, weighing at 178 g per sandal (356 g per pair in size 9). This makes them ultra-light and compact, perfect for bivouacking hikes where space is limited.

Sizing and Fit Advice 📐

Finding the perfect fit for your barefoot sandals is essential for a comfortable and enjoyable journey on the trails. Let's discuss sizing advice for the Oso Flaco Winged Edition and the Forclaz Trek 500 to help you make a confident decision.

For the Oso Flaco Winged Edition, most men tend to size down 1/2 to a full size. On the other hand, most women find that their regular size fits just right.
