* Handcrafted in Portugal
* Made for Running, Hiking, and Skiing

Fit:
* The Cascadia is their 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: their insoles come in full size runs. No trimming. No fuss. If you wear a half size shoe, they generally recommend you round up to the nearest whole size.

Materials:
It's a Material World:
* They spend a lot more on materials than their competitors. Why? Because the best materials deliver the highest performance and long-lasting durability. It's a no-brainer

Sustainable Natural Cork:
* They source 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 their 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

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 their entire operation is off-set with carbon credits. They also use natural cork in Their insoles in place of petroleum-based plastic (or EVA) that is commonly used by other brands. The factory in Portugal is powered in part by bio-mass (cork dust). That's as clean as it gets. Beyond that, their packaging is minimalist
