Some people call it a daily driver ? we call it the Circadia. Featuring a lightweight KEEN LuftCore cushioning this is an everyday hiker with all-day comfort and protection. Made with durable leather, breathable vented mesh and featuring a high-grip tread, the Circadia Vent hiking shoes for women are built off KEEN's traditional wider footwear form. KEEN products are consciously created using PFC-free water repellent (in applicable styles) and leather sourced from Leather Working Group (LWG)-certified tanneries. KEEN makes shoes to make a difference. As a brand born for life outside, KEEN has a responsibility to protect and conserve the places where all people live, play and work with no ceiling.
