As a woman everyone wants to be graceful and have a nice figure. High heel shoes contribute to that. As teachers we want to show students not only that we have expertise/competence but also that we have a style. After a long time no high heel shoes, my feet were very tired of being in my shoes all day at work in the last week. Even the shoes are old. Strange. Perhaps, my feet get used to comfortable casual sandals, not like the forms of the shoes any more. :-). Time to change.
