Working an all-nighter in a hospital can certainly put a damper on things (to say the least), which is why fun, on-call footwear is absolutely essential! A print or textured shoe may attract odd glances and double-takes, but the sky is the limit when it comes to socks. Enter: My husband's wide array of stripes, polkadots, paisleys, and houndstooth. These prints lend a pop of vibrant color, yet are subtle--peeking out only every now and then. A perfect pick-me-up for doctor and patient!
