These beautiful cozy slippers are made from 100% recycled items If you like to keep you feet toasty warm, these are for you. The exterior is made from 100% wool coats that have been felted down via “boiled wool” method and then hand dyed, to achieve the wonderful colors. The soles are made from an anti-abrasive synthetic suede made from recycled plastics, and they are skid resistant also! The linings are from fleece clothing and throws, that have been cleaned and reused. The faux fur inside the ankle section of the toasties is super soft and comfy. NO ANIMALS were harmed in these Toasty boots. These lovely little gems are MACHINE WASH COLD and TUMBLE DRY. For BEST drying techniques, after washing place boots upside down over a floor heater vent to help dry the toea area better, BOOT DRIERS are excellent for drying the insides of these slippers. If neither of these are options for you, try and turn the toe inside out after washing then pop in the drier…….as your toe area will be a little harder to get drier. Your feet will love the little hugs from these cute slippers.
