These shoes are great for going through security at airports, and also when on board the plane. Comfortable, light-weight, nice colors, easy to stash in a pocket or purse. The soles are a bit thin so they fold easy, which is great if you don't need to do a lot of walking, but they are not cushioned enough for sufficient foot support in extended walking.
Also, if you plan to wear warmer/heavier socks with them (like on the plane), you may want to order 1 size up for better fit. I love these flats for air-travel that doesn't involve long-distant walking, and they look nice with stockings for casual wear anywhere also.
