Comfort and function merge in the feminine KEEN Whisper sandal. The synthetic webbing upper features straps designed to fit anatomically with your foot; a quick-draw elastic cord lacing system lends a snug fit. The hydrophobic mesh lining provides water resistance, while the antimicrobial Aegis Microbe Shield� treatment fights odor to maintain a fresh interior. A metatomical EVA footbed offers long-lasting comfort. The textured rubber outsole of the KEEN Whisper sandal provides traction on a variety of surfaces. Fit tip: This sandal runs true to size and narrower than the classic KEEN fit.
