Shamma - Pacific Avenue - Leather - Tan (Unisex)

Running sandals, also known as athletic sandals, are nothing new—they’ve been around for thousands of years. From marathon-running Greeks to Roman warriors, sandals were once designed for serious movement, not just lounging around.

These days, we’re bringing that natural freedom back. With your feet open to the air, your toes can spread, you sweat less, and you avoid the painful blisters that come with closed shoes. Even better, your feet get to move the way nature intended—supporting your balance, coordination, and whole-body alignment.

Shamma Sandals are crafted to move with you through every adventure—from running and lifting to hiking, kayaking, and even obstacle races. If they’re secure enough for running, you can trust them for just about anything.

At first glance, a lot of running sandals look alike. But once you slip on a pair, you’ll feel the difference. Shamma Sandals are all about striking the balance—giving you full freedom of movement while keeping your foot locked in and secure.

From high-quality materials (even military-spec thread) to custom machines designed to eliminate hot spots, every detail is crafted for comfort and performance. The result? Sandals so minimal and natural-feeling, you’ll forget you’re even wearing them.

The size chart for each product shows the sandal length and width of each shoe model (US sizes). We recommend approx 12mm of space in front of your toes (no less than 6mm and no more than 18mm). Refer to our comprehensive Find your Perfect Fit page for guidance on exactly how to measure your feet and choose the right size.

Shamma Sandals are unisex and use proprietary Shamma Sizing. This makes it easy to find your perfect fit, no matter your foot shape.

That depends on where your adventures take you. Each sandal has its own strengths, whether you’re looking for more ground feel, extra grip, or something built for wet conditions. On every product page, you’ll find clear details on the sole, footbed, and lacing system to guide your choice.

Tip: Use the menu to browse sandals by activity—it’s a simple way to find your perfect fit.

Not at all. While they’re amazing for running, they’re built for all kinds of movement and everyday wear. Wear them on a hike, a walk through town, or just to kick back. They’re performance sandals that keep up with your lifestyle.

Yes — especially the UltraGrip models, which are waterproof, quick-drying, and ideal for everything from stream crossings to rainy adventures.

Leather editions handle normal foot sweat well, but they don’t love being soaked. Wet leather can feel slippery and may change color, which is totally natural for that material. For full immersion (like swimming or river trekking), pair your sandals with Power Straps for extra hold.

Not long. Within a few days, the toe strap will soften, followed by the heel straps and laces. Around the 1–2 week mark, the soles will mould beautifully to your feet, and by 3–4 weeks, they’ll feel like a second skin. Think of it as your sandals “hugging” your feet—like finding your favourite spot on the couch.

Nope. Toe plugs are counter-sunk and sit flush with the sole, so you won’t notice them. The only exception is with Warriors soles, where you might feel the plug briefly during break-in. Once the sole forms around your foot, it blends right in.

Yes — they protect while still giving you that barefoot ground feel. The Warriors sole offers the most natural connection to the ground, while the TrailStar Omega sole provides the most protection. Over time, the sole moulds to your unique footprint for a custom fit.

Not at all. Shamma laces are built tough and last as long as the sandal (and usually beyond). Even if they graze the ground, they won’t wear through thanks to the way the sole lifts and protects them.

They’re made to last, but a little care keeps them happy:

• UltraGrip sandals: Wash with cool water and mild soap if needed. Air dry away from direct heat, sunlight, or steam.
• Leather sandals: Use a suitable Leather Cleaner + Conditioner for the best results.

Tip: Avoid leaving your sandals in extreme conditions (intense heat, cold, or moisture). They’re fine on your feet during adventures, but storing them in harsh conditions can damage their shape or materials.

All UltraGrip top models are vegan. Just look for the UltraGrip footbed option when choosing your pair.
