Mules are the perfect shoes for transitional weather. They’re chic, comfortable, come in all different heel sizes from thick block to vintage kitten, and you can wear them barefoot, with tights or bright colored socks. While the trend has been going on for a few seasons now, designers are still creating fresh iterations for spring that will make your wardrobe look brand new without much effort. Shop from our favorite spring mules, all under to $600.
