Our Instagram Saved collections and Pinterest boards may be brimming with strappy stilettos and intricate lace-up heels, but let's be honest: Slip-on shoes are what we wear most. From mules and loafers to slides and classic flip-flops, these are the shoes we turn to when running a quick errand, grabbing the mail, or even dressing up a casual jeans-and–white-tee ensemble.
Suffice it to say, it's important to select the most comfortable, long-lasting, and high-quality styles when shopping for slip-ons. We took it upon ourselves to scour our favorite retailers in search of just that, and we weren't disappointed. Below, shop the best slip-on shoes on the internet—whether you're looking for flats, heeled sandals, mules, sneakers, or loafers.
