PEOPLE joke that you know you’re an adult when you start wearing slippers around the house and then later when you start asking for a new cozy pair with a sturdy sole every Christmas to replace the pair you’ve worn out from wearing every day, lest your bare foot touch the chilly ground in the kitchen. But in reality, we’re not all slipper people. Instead, some of us are buying Amazon’s best-selling sock-shoes.

With over 2,000 reviews, this conundrum of footwear, known as FitKicks, is basically a pair of super durable socks made from water-resistant athletic material, and they give you all the slip-on comfort of wearing socks around your house, but with extra support and grip to ensure you don’t slip or injure yourself. Thanks to a sturdy rubber sole, they can also be just as useful for those pursuing active ventures like yoga and kayaking. Coming in 16 different colors and patterns, as well as sizes small to extra large, FitKicks seem to have something for everyone, and reviewers note that the sock-shoes run generally true to size.
