When you are flying, comfortable shoes are a must. Think about carrying those heavy suitcases and the long walks inside the airport, and you will forget about wearing those high heels. Still, don’t forget that comfortable shoes can still be stylish. This is exactly what the Adidas sneaker is there for.
Simply put, you do not want to put on a pair of shoes that will make your feet cry after just a few minutes. Of course, you do not want to want to have to lug around an extra pair just to have something else to wear once they do. So the easiest option is to just get the right pair for your whole trip and leave the heels for a formal dinner date.
While sneakers might be seen as too casual, you need to look at some of the Adidas pairs that are not flashy. This way, you can still wear them with a dress or a more classy suit. The lightweight and soft structure will also keep you comfortable while walking all over the airport.
In short, it will be like wearing your tennis shoes but still being able to stay fashionable while traveling. It is really not rocket science; simply common sense.
