Our insoles are designed in Bend, Oregon & handcrafted in Portugal.

Cork is 100 percent sustainable & 100 percent awesome. We use cork in place of petroleum-based plastic and EVA that many brands use. For more information about cork, you can read about Tread & Butter’s commitment to sustainability.

Our insoles are intentionally-designed for sport, work and outdoors. Meaning, our insoles are perfect for running, hiking, skiing, etc. And equally great for standing, working on your feet, retail, waiting tables, commuting, etc.

Tread & Butter insoles come in whole sizes for women and men. If you typically wear a half size shoe, we recommend rounding up to the nearest size.

Please consider the type of footwear you will using with your Tread & Butter insoles. Performance & athletic footwear (running, hiking, sneakers, etc) generally fit slightly bigger and can accommodate our insoles. Some dress and casual shoes (slip ons, loafers, boots, etc) tend to fit a bit smaller and might be difficult to fit with our insoles, or any other aftermarket insole. Questions: please contact us.

Yes. In most performance footwear like running shoes, hiking boots and sneakers, it probably won't be necessary. Occasionally, narrow-toed shoes & boots will require you to trim the toe area of your insole for the best fit. The key is to use a sharp pair of scissors and trim around the toe area. We suggest you only trim a little bit at a time and try them on for size (obviously cutting too much is not good). You can trim a little more if necessary. If you have any questions, please feel free to contact us and we'll be happy to walk you the simple process.
