Fit for the trail, the beach, the climb, and the city, Senja is a waterproof shoe that keeps you cool, dry, and comfortable no matter the season or the terrain. You’ll feel amazing in Senja, and not only for its FlexForm slip-on comfort. Senja is made from eco-friendly materials so you can wander far, free, and sustainably into the future.

Senja were designed for all types of terrain and every climate. Their unique features protect your feet in any environment, from snow-covered peaks to sandy beaches to mossy rainforests. Whatever your adventure, Senja will take you there.

Senja’s global-friendliness comes from years of engineering and design, but we have to give a shout-out to our most important contributors: Merino sheep. These sheep provide the wool that gives Senja their strength, comfort, and so much more. 

Senja is 100% waterproof, highly breathable, and moisture-wicking to protect against rashes and odors. How did we do it? We invented our own brand new FlexForm fabric only found in Senja. 

We took all the elements we loved from our favorite shoes—hiking boots, running shoes, water shoes, work boots, and even slippers—and put them into a shoe you can wear every day. 

Wear Senja in the shower, the rain, or diving. Our FlexForm design will keep your feet dry even when fully submerged. Don’t let moisture, mud, or weather stop you. Go further with Senja, the most advanced adventure footwear on the planet. 

With Senja, your feet are 100% protected against water and moisture. It doesn’t matter if you’re free diving in the Mediterranean or splashing in a sidewalk puddle; Senja’s FlexForm fabric hugs your feet and doesn’t let a drop of moisture enter from top to bottom.

Other waterproof shoes are protected by a spray or coating. Senja’s waterproofing is built into its very fibers, meaning its waterproofing power will never fade over time, lasting the lifespan of the shoe. 

Senja’s SoleCast cushioning is calibrated to your movements, absorbing maximum shock to protect your ankles, shins, and knees. Its FormFlex fabric and moisture-wicking properties also protect against blisters, calluses, irritation, and athlete’s foot— with or without socks. 

Senja are high-performing shoes capable of meeting the needs of the most active people and athletes. Made with custom cushioning that adapts to your pace, Senja delivers all-day comfort with a boost of energy return on each stride. 

Senja are so comfortable, you’ll want to curl up with them even when you’re not out exploring. Perfect for lounging and relaxing, Senja are the flexy slip-ons you’ll never want to slip off. 

Senja’s interior is made of 100% Merino wool. We’re proud to use an ultra-fine material that strikes a balance between high-tech functionality and Earth-friendly design.

Merino wool is a rare type of wool shorn only from Merino sheep. Its ultra-fine fibers make it unlike any other wool on the planet. Soft, insulating, protective, and long-lasting, Merino wool is the highest performance fabric of the 21st century.

Shorn from Merino sheep using sustainable shearing practices, Merino wool gives you the comfort and protection they need to round the globe while doing your part to protect it. Happy sheep make happy feet!

Merino wool is full of tiny air chambers that help to regulate temperature and control airflow. This means your feet will feel cool and comfortable in the summer and warm and cozy in the winter. 

Merino wool insulates your foot to keep it at a comfortable temperature no matter the weather conditions.

Merino wool’s ability to release moisture and heat make it one of the most breathable materials on the planet.

Keep your feet and shoes clean, comfortable, and free from odors caused by bacteria and mold.

Merino wool is resistant to microbial life, meaning no harmful bacteria, allergens, or fungus can find a home in your shoes or your feet (no more athlete’s foot!). 

Our SoleCast Marino wool is one of the most durable fabrics you can get your hands on. Thanks to the wool’s interlocking structures of keratin molecules and our custom SoleCast weave, our Merino wool interior is able to bend, stretch, and flex while holding its original shape longer than any other fabric.

This isn’t the itchy Christmas sweater you were forced to wear for grandma! Merino wool is incredibly comfortable because of the smooth, ultra-fine wool fibers produced by Merino sheep. 

Merino wool is as comfortable and luxurious as cashmere.

Senja’s footbed is made of high-performance and long-lasting 100% Merino wool. But, if you prefer a different insole or have orthopedic needs, the wool insole is easy to remove and replace. 

Tired of smelly shoes and socks? Ditch the itchy powders and sprays for good with Senja. Wear with or without socks; Senja’s anti-odor and antimicrobial fabric will leave your feet feeling dry and smelling… well, as good as a foot can smell!

Senja is made with moisture-wicking material that absorbs and releases sweat through fibers on the outer part of the shoe. Your feet are guaranteed to be fresh and dry even after the toughest hikes and the hottest days.

No need to quarantine Senja when you’re not wearing them. They stay clean and odor-free at all times.

A shoe’s comfort directly correlates to its weight. The lighter, the better. Thanks to ultralight Merino Wool, Senja are lighter than other all-terrain shoes. Have you ever felt like you’re walking on air?

In the past, active people have chosen heavy shoes for their durability and weatherproofing—but at the expense of comfort. Ouch! With Senja, you can walk all day pain-free and never worry about blisters and soreness developing over time.

Whether you’re going east, west, vertical, or horizontal, Senja’s non-marking rubber soles provide excellent traction to prevent injury and slipping.

From kitchen and bathroom floors to icy roads to stony cliffs, you can take every stride with confidence in shoes that were designed for your safety.  

Wear Senja on hard floors and wood without the risk of leaving ugly streaks. Senja’s soles are made with non-marking rubber.

According to scientists, flexible shoes are the healthiest for your feet. And it makes sense, doesn’t it? Why choose a shoe that restricts your feet when you could enjoy form-fitting flexibility that liberates your movements?

Senja’s FlexForm comfort allows for a natural stride that fits your body. The Merino wool interior is also much thinner than other footbeds, allowing for a natural stride and healthy contact with the ground on each footfall. It also helps prevent stress on your joints and tension in your arches

Our FlexForm material always pops back into place no matter how you flex it. So go ahead and twist and fold your Senja shoes—it makes them perfect for packing!

Senja’s material is stretchy and soft. It’s about time a shoe adapted to your foot and not the other way around!

Senja’s breathable FlexForm fabric releases moisture with every step, leaving your shoes dry within minutes of leaving the beach or the shower. 

We know your adventures sometimes go off-road, so we made Senja stain-proof and dirt-proof. From dirt biking to tug-o-war to getting down and dirty cleaning up the local river, Senja will look as good as new when you get home. 

Just rinse and you’re ready to go! Moisture-proof fabric ensures that any dirt or grime will rinse off with no scrubbing necessary.

Light and breathable shoes can often leave your feet with the chills in the colder months. But not Senja.

Senja are temperature regulated and windproof, leaving your feet toasty in the winter and preventing the wind from numbing your toes.

The footwear industry is one of the most polluting industries on the planet. Did you know it takes fossil fuels, animal products, a cocktail of toxins, and thousands of liters of water just to produce one pair of shoes?

Senja’s manufacturing process has been completely revamped for sustainability from start to finish. Using only sustainable materials and Merino wool sheared using sustainable methods, you can be sure that when you wear Senja, the only footprint you’ll leave is your own.

Senja was designed with sustainability in mind from heel to toe. We painstakingly designed and tested dozens of different fabrics, designs and styles to create an optimized design and material mix to reduce waste as much as possible.

Along with our sustainability focused design, Senja’s manufacturing process has been completely revamped for sustainability from start to finish. 

Social responsibility, fair working conditions and welfare of all our employees – along with those associated with us – is also super important for Senja. We work only with manufacturers and suppliers that are paid living wages, which also results in happier, more productive and higher quality workers. 

Senja exclusively uses cruelty-free wool from small farmers with stringent animal welfare requirements. Don’t just look good with Senja, but also feel good.

We take every step to ensure you can explore the planet with respect. And in a pair of Senja, you can take same steps every day.

If a shoe is recommended for sizes 41-42 and your perfect fit, according to your measurement, is a 42, we recommend sizing up to a shoe made for a 42-43 size foot to ensure optimal comfort.
 

Senja is manufacturing-ready and ships when the campaign ends. Get your pair today and don’t miss out on exclusive early bird pricing.

The Senja team loves shoes. Maybe a little too much, actually. When we realized how many shoes were in our closets, we were a little embarrassed. Then, when we found out the damage that manufacturing all those pairs did to the planet, we were shocked. We knew there had to be a better way.

So, we started to think: What if we could put all the best features of our favorite shoes into one, year-round, all-terrain package? Waterproof, windproof, comfortable, athletic, safe, stylish, and more. 

But we didn’t just want to reinvent the way we wear shoes. We needed to change the way footwear manufacturing practices were affecting the environment. 

It took years of dreaming, planning, development, and testing, but we are finally ready to release Senja, the most versatile eco-friendly footwear on the planet. 

We’re proud of our work on Senja, and we hope you’ll be proud to back a shoe that perfectly fits your feet, your lifestyle, and the move to a cleaner planet. 

The Senja family is comprised of footwear enthusiasts around the world. We are top designers, engineers, ergonomic specialists, scientists, and adventurers, all putting our heads together in our offices in Hong Kong to build a better shoe and a better world.
