Every once in a while—and especially during the winter, when cold-weather footwear is of paramount importance—a new shoe style comes seemingly out of nowhere, ostensibly designed to withstand frigid temperatures, that is equal parts polarizing and covetable. In the early 2000s, the style in question was undoubtedly the Ugg boot, a controversial yet indisputably comfortable trend, once rejected and now beloved by industry insiders. Then came the Croc, a utilitarian staple akin to a rubber clog that has since been given the high-fashion treatment by the likes of Balenciaga and Christopher Kane. This time around, there’s a new contender: Introducing the “sluffer,” a portmanteau of slipper and puffer, and pretty much the only shoe we’re eyeing as we continue to redefine our style amid the ongoing pandemic. Striking an oddly attractive balance between functional and fashionable, the sluffer can be worn inside or outside; in the mountains or on the street. It makes sense, then, that brands from Teva to Prada have introduced variations on the trend. And in case you need further proof that the sluffer is the It shoe of 2022, look no further than Kendall Jenner wearing them in the wild. Her sluffer of choice: The North Face Women’s Thermoball Traction Mule V, a padded slip-on that’s essentially like wearing a Bottega bag on your feet. If you’re a strict no-shoes-inside-the-house family, we totally get it: Wearing your shoes inside can feel like you’re bringing the dirt, mud, and grime of the outdoors into your clean home. Plus, who wants to wear their work heels, walking shoes, or sweaty gym sneakers inside, anyway? But, as it turns out, going barefoot at home actually isn’t great for your foot health. Thankfully, there’s an easy solution: wearing comfy, cushiony indoor slippers with arch support.
