I actually bought some soles for my shoes in Stockholm. I always wear these Asics, all-white, simple tennis shoes. They're really nice and good-looking, go with anything you wear, but they have very thin soles. So your feet ache a lot from walking around in them. So I just bought these soles, and suddenly I can walk around in the city for a whole day without aching. It was such a simple thing to do to make my life so much better."
