The SFB (Soft Footbed) acronym means a footbed with an extra soft layer, providing immediate comfort from the very first wear, ideal if you're on your feet for many hours. The tonal Carafe (warm dark brown) suede upper gives a clean look that's super easy to pair with denim, cargo pants, shorts, and natural palettes. The narrow fit is designed for narrower feet or for those who prefer a more snug fit. SKU: 1031640 NARROW FIT
