As a rule, it looks good with light evening shoes. Tread feels secure (doesn't slip on standard vinyl floors). Noble inserts are comfortable. The length seems correct for size 9 (US) shoes. The toe is narrow. The fit isn't as roomy as comfy croc clog sneakers or sandals/water shoes, so for me the fit is a bit snug and doesn't slip easily. I prefer a D or "medium width" to allow my toes to move freely.
