Newly streamlined designed with all the solid, reliable and stress-free features you’ve come to love from the original KEEN Kaci shoes. They’re the support system you've been waiting for. Credit goes to all sorts of comfort features, from the roomier rounded toe (a KEEN exclusive) to a footbed anatomically designed for enhanced arch support. Mesh lining lets feet breathe a sigh of relief, and the compression molded EVA midsole and rubber outsole absorb endless pavement pounding.
