Updated fit and streamlined design 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.
