Sierra are high, handcrafted in Poland barefoot hiking boots for her and for him — lightweight, ultra-flexible, and surprisingly durable. You get the full “barefoot” experience (zero-drop, wide toe box, natural movement) along with solid protection for real terrain: an oiled nubuck upper, a breathable membrane for rain, and a sole that bends like no other on the market. The result? Your feet move as if barefoot, your body moves naturally and freely — in autumn and winter, in the city and on the trail.

Trail-city barefoot! – a functional “trail-city” form that performs bravely on the trail and looks great in everyday use. Breathable barrier for harsh conditions – the TE-POR Water Resistant membrane blocks moisture from the outside without creating a “sauna” effect inside. Natural biomechanics – a completely flat, flexible sole and spacious toe box for full control without any barriers. Protective outsole edge – the lower part of the construction is less prone to scuffs and dirt while maintaining top-level flexibility. Materials made to last – oiled nubuck withstands everyday wear and off-road challenges for years.

Handcrafted in Poland with attention to every stitch. You get boots that don’t “pretend” to be outdoor gear — they simply perform: lightweight, flexible, ready for the trail yet perfect for the city. No fancy “systems,” just pure biomechanics. Put them on, and if you’ve never worn similar shoes before, you won’t believe what just happened.

Sierra is a fully barefoot shoe for special tasks: zero-drop, a wide toe box, and an exceptionally flexible sole. Compared to classic trekking boots, it doesn’t stiffen your foot unnecessarily, doesn’t lift the heel, and doesn’t squeeze the toes. The result? A natural posture, fully controlled steps, and noticeably less fatigue on long routes — as if you were walking barefoot, but with the protection you want in the outdoors.

The upper is made of oiled nubuck leather, combined with a breathable membrane and details that make a difference: waxed threads, sealed lining seams, a gusseted tongue, and sturdy lace hooks. The raised sole edge protects the lower part of the shoe from mud and scuffs, and the whole shoe is easy to clean after a hike. These are boots for more than one season — designed to join you on many trails to come.
Sierra combines craftsmanship, durability, and the freedom you expect from true outdoor footwear. Made from oiled nubuck leather, flexible and weather-resistant, they provide natural comfort with every step. The breathable TE–POR membrane keeps your feet dry and fresh, while the flat, flexible sole lets you feel the ground and stay stable on any terrain. Sierra are shoes that simply work – reliable, comfortable, and in harmony with nature.

Sierra fits your foot like a perfectly tailored jacket: nothing rubs, everything moves with you. The zero-drop (0.0 mm) keeps your posture straight, the wide toe box lets your toes spread like a fan, and the exceptionally flexible sole bends with every step – allowing you to control your footing more easily and use less energy on long climbs.
The oiled nubuck upper withstands abrasions, wet grass, and rocky trails, while the Water Resistant membrane with a textile lining blocks moisture while allowing your skin to breathe. Waxed threads, sealed lining seams, and a gusseted tongue protect the interior from mud, sand, and snow. The insole – cork + foam + microfiber – smooths out micro-shocks and shields you from sharp stones without reducing ground feel.

The tread pattern is designed to stabilize your step on varied terrain, improve mud and water drainage, and maintain springiness so your foot can quickly “read” the ground. The raised sole edge forms a protective barrier around the upper – fewer random scuffs and easier cleaning after the hike.
The oiled nubuck leather and the membrane lining limit water penetration from the outside while allowing free airflow. Regular waterproofing enhances protection in prolonged moisture. The shoes are not fully waterproof.
Autumn and winter with moderate frost. Thermal comfort up to approx. -6°C with suitable socks.
Yes. These are the most flexible hiking and trekking boots available on the market. The sole bends extremely easily, helping maintain a natural gait and precise step control.
They combine zero-drop (completely flat sole) with a wide front and flexible construction. The foot moves naturally, posture stays upright, and the tread helps maintain smooth motion on varied terrain.
Measure your foot while standing and add 6–8 mm of space. If you’re between sizes, it’s usually better to choose the larger one. If you plan to wear thick socks, add another 2 mm.
Oiled nubuck leather, TE–POR Water Resistant membrane, textile lining, waxed threads, sealed seams, and gusseted tongue; insole made of cork + foam + microfiber (removable).
Yes, the insole is removable; however, remember that barefoot shoes have a wide toe box, so “regular” insoles will likely be too narrow. Also note that the barefoot concept is based on the natural movement of the foot — use additional support only if recommended by a specialist.
