I regularly hear from people who think their feet are too big. In some cases, these people actually have real difficulty finding shoes that fit -- or at least finding attractive shoes that fit. But there is another group that can easily find footwear, they're just self-conscious of the fact that their feet seem too big for their body, or for their taste.
The first thing I tell members of the latter group is that their feet probably don't look as big to others as they do to themselves. The second thing I tell them is to look for different shoe styles.
