Targeted support for high arches. Built to perform.
High Arch Cortiças are high performance cork insoles designed specifically for high arches and demanding days. Ideal for athletes, professionals, and anyone who spends long hours on their feet, they deliver structured support that helps improve posture, reduce strain, and maintain comfort throughout the day.
Designed with high arches in mind, these insoles provide targeted reinforcement where it is needed most, helping distribute pressure more evenly and support natural alignment without feeling rigid or restrictive.
Crafted in Portugal from regenerative Mediterranean cork and upcycled shoe waste, High Arch Cortiças combine durability with sustainability. They are carbon negative, fully recyclable, and naturally antibacterial, offering high performance comfort with a low environmental footprint.
Lightweight, breathable, and built to last, these insoles are made for people who demand more support without compromising on responsible materials.

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...
