Insoles for The Outbound

The Cascadia is our flagship high arch cork insole. The fit is exquisite, especially for people with high arches. If you need a low arch insole, we recommend the Suntoucher. We should definitely mention our insoles come in full sizes for women and men. No trimming, no fuss. And this is important: your feet are dynamic, they move and flex. That's a good thing. Our insoles are designed to provide support under normal load but are oh-so-forgiving when your feet need a nice, soft landing. It's the ideal balance of ergonomic support and plush comfort.

• Free Shipping/Free Returns

• Designed in Bend, Oregon

• Handcrafted in Portugal

• Made for Running, Hiking, and Skiing

The Finer Details

    Fit

    The Cascadia is our high arch cork insole, made to keep your arch elevated and help mitigate foot pain caused by maladies like plantar fasciitis. And this is key: our insoles come in full size runs for women and men. No silly unisex sizing. No trimming. No fuss. If you wear a half size shoe, we generally recommend you round up to the nearest whole size. Done. That's it. Plug and play victory for your feet. 

    Materials

    It's a Material World: We spend a lot more on materials than our competitors. Why? Because the best materials deliver the highest performance and long-lasting durability. It's a no-brainer for us. 

    Sustainable Natural Cork: We source our cork from the fabled cork forests in Portugal. It's supple, light, and most importantly, it feels great under your foot. Say goodbye to bad plastic insoles.

    Odor-Crushing XSTATIC®: See the subtle pinstripe on the top of our insoles? That's a silver coated thread that disperses tiny bacteria-killing ions across the entire surface of the insole. Kill bacteria, and you kill odor. XSTATIC is bluesign® approved. If your feet stink, it won't be our fault.

    Unbeatable Poron Vive® Cushioning: This is the most plush, highest rebound cushioning on the market. It can't be beat. Your feet will never let you use a generic, crummy foam insole again.

    Sustainability

    Tread & Butter is Climate Neutral Certified. Which means our entire operation is off-set with carbon credits. We also use natural cork in our insoles in place of petroleum-based plastic (or EVA) that is commonly used by other brands. Our factory in Portugal is powered in part by bio-mass (cork dust). That's as clean as it gets. Beyond that, our packaging is minimalist, we specifically off-set our outbound shipping, and we make every effort across all aspects of our business to reduce our carbon footprint. It's fully baked into our DNA. We're all-in on sustainability.

    * Size notes: Our insoles run 'true to size' for performance footwear (e.g., running shoes, hiking boots, etc). We offer a complete size run for women & men. If you typically wear a half-size shoe, we recommend that you round up to the next size; e.g., 7.5/8, 8.5/9, 9.5/10, etc. Questions: hello@treadandbutter.com
