So these shoes are cute and they are a great idea. However, the drainage holes on the bottom insert are not designed for comfort. The holes will actually hurt, blister or agitate your feet with any wearing because your flesh pushes down into the holes. Ouch. Ouch. Ouch. I was really bummed out about this because they were cute for a simple shoe to wear when you might get a little wet. Not designed for trails or hiking even if they holes weren't painful. Bummer on the drainage feature that turned out to be a blister potential.
