We strive to have comfort down to a science by constantly tweaking our proprietary memory foam insole technology, which is the secret ingredient found in all of our superbly comfy, ahh-inducing footwear We're committed to making slippers that last, breaking the conventional 6-12 month life expectancy for a pair of slippers. This is achieved by sourcing quality materials, and also making every pair machine washable; you can easily clean them and they'll come out like-new after every wash.
