Primal Black | The Ultimate Cork Insoles
Supports the arch of the foot
Prevents foot, knee and back injuries
Improves comfort and skeletal alignment
Maximum Comfort. Minimal Footprint.
Designed for those who spend long days on their feet, the Ultimate Cork Insoles combine the natural performance of premium Portuguese cork with advanced cushioning and lasting support. Every step feels lighter, more stable, and more comfortable, whether you're exploring the outdoors, travelling, or simply moving through everyday life.
Naturally supportive cork moulds to the unique shape of your feet over time, while helping regulate temperature, wick away moisture, and minimise unwanted odours. A high performance cushioning layer absorbs impact without compromising stability, reducing fatigue from the first step to the last.
Made in Portugal from regenerative cork, these insoles are engineered to perform while leaving a lighter footprint on the planet. Lightweight, breathable, and exceptionally durable, they are designed to keep you comfortable wherever life takes you.

What size should I choose?
We recommend choosing a slightly smaller size than your shoe size. However, if your primals do come a bit too big, you can always customize the size by placing the existing insole over your primals and cutting along its edges. Every shoe is different after all...
Should I remove my current insole?
This depends on your preference. In general, we see that our customers replace the existing insole with their new primals. However, especially in boots, some like to double up. Every shoe is different after all...

Founder's Guarantee
How primal is your sole?
We started Primal with a simple idea: to offer maximum comfort to explore our natural world while leaving a minimal footprint behind.
That’s the simple standard we hold ourselves to with every product we design. A guarantee made from two brothers to you. Let's make every step a better one.

“After meticulous testing, I can’t go without them anymore! I can feel the isolation and at the same time the grounding, and the most magical part is that it is a natural product and I think that is why I’ve got this great sensation. So from my end it is a 10 out of 10.”

I appreciate that they are biodegradable and thoughtfully made. Comfortable enough to wear for hours without thinking about it.
