I bought these shoes primarily as indoor shoes. Comfortable with a soft sole. Feet breathe a little accumulation of sweat. BUT I live in the country and have a gravel driveway. As others have noted, the cushion design on the soles picks up a lot of pebbles. Every time I step into a gravel driveway, 2-3, 1/2 inch pebbles in each shoe. I don't like stepping barefoot on 1/2 inch pebbles. You should rename them Pebble Poluza. I wanted comfort but wouldn't buy Poluza because of the Pebble.
