With the recent rainy-day forecasts, Loeffler Randall's new rain boots couldn't come at a better time. Designer Jessie Randall — seen here splashing in puddles — just released a cool, new slip-on bootie style in navy and black. They're super functional, and we love the clean, minimal design. "It's so easy to get on an off," said Randall. "The perfect thing for running out the door." We agree. And if you're looking for a cute umbrella, Randall dished on a recent awesome find: "I found a really cute umbrella at American Apparel that has a lace pattern edge. It is delicate and functional." Check out the slip-on rain boot styles in the slideshow, plus see the popular lace-up bootie in a new gorgeous gray hue.
