The Crackle mule slipper is definitely a purchase to make for this season, the colours just pull us in. With super soft trims and a padded insole, we can't get enough of this slipper. The slippers should be washed in a pillowcase and washed at 30 degrees and allow to dry naturally. Do not tumble dry or force dry and this will misshape the slipper and damage the textile upper.
