Carrying my shoes home. I love wearing heels but because I walk everywhere living in Melbourne, I pack flats to walk back home. I'm not too shabby though with lasting in high heels. I always pack those gel ball of your foot things but the trick is, you put them in your shoes AFTER you've been wearing them for ages and they give your feet a second life. Sneaky hey? I also wear my high heels around the house with socks to wear them in.
