Soft comfort. Natural support. Zero bulk.

Low Arch Bananas are flat cork insoles designed specifically for low arches and those who prefer a more natural, minimalist feel underfoot. They deliver all day comfort without overcorrecting your stride, making them ideal for everyday wear.

Crafted from regenerative Mediterranean cork and upcycled shoe waste, these insoles combine softness, durability, and sustainability in every step. The surface feels soft and slightly squishy at first touch, while the cork core provides stable shock absorption that holds up throughout the day.

As you move, Low Arch Bananas naturally mold to the shape of your foot, creating personalized comfort over time. Whether you are standing for long hours, walking through the city, or constantly on the move, they help reduce pressure and fatigue while keeping your feet grounded.

Lightweight, breathable, and naturally antibacterial, these cork insoles stay fresh and comfortable without adding bulk to your shoes. Designed for people who want subtle support, not rigid structure.
