Women's Vionic Willa 2.0 Loafers This flat brings together an easy slip-on entry with a softly tailored shape that works from office to off-duty. The man-made upper creates a smooth, refined look, while the almond-shaped toe keeps things modern and comfortable. A cushioned insole gives gentle support for long stretches on your feet. With its low, barely-there heel, this style feels as effortless as it looks.
