I bought these primarily as indoor shoes. Comfortable with a soft sole. Feet breathe a little without sweating. 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 shoe. I don't like stepping barefoot on 1/2 inch pebbles. You should rename them to Pebble Poluza. I wanted comfort but wouldn't buy Poluza because of the Pebble.
