I bought these shoes primarily as indoor shoes. Comfortable with a soft sole. Feet breathe a little, no sweat accumulation. BUT I live in the country and have a gravel driveway. As others have noted, the support block design on the soles takes up a lot of pebbles. Every time I step onto a gravel driveway, 2-3, 1/2 inch pebbles in each shoe. I don't like stepping on 1/2 inch pebbles with my bare feet. You should rename them to Pebble Poluza. I wanted comfort but wouldn't buy Poluza because of the Pebble.
