I purchased this product after being forced into the typical slippers available that are made of synthetics. The synthetics not only caused my feet to sweat, but smell. These slippers have neither of those attributes and would highly recommend them. They are warm (even standing for brief periods while BBQing in the snow) and sized well (although when first tried on they seemed a little small, but as will all natural materials will increase in size slightly to fit your foot). I'll never go back to synthetics again. They arrived promptly and in good condition.
