I developed plantar fasciatis (spelling) a few months ago, and so I had to replace my normal house slippers (the kind you can buy anywhere for about $10) with something that provides more support and comfort. I had a pair of the "classic brand" indoor/outdoor green shoes with holes, and they are great, but I wanted something warmer for winter. These DAWGS so far have worked very well, but I have not yet washed the fleece lining. I wouldn't recommend wearing them outside because the fleece could easily attract dirt, burrs, etc., but they are fine for occasional outdoor use (such as a deck or sidewalk, I suppose).
