We are rarely shoe-less in our household. Off go the outside shoes, on go the inside ones, whether they are crocs, slippers, moccasins...I sew with footwear on at home and at classes and retreats. I don't recall anyone not wearing footware at the last couple of retreats, we were all in shoes of some sort...except when we were in the hottub...but it was snowing and we needed boots to get to the tub.
