Elephant Shoes

So I pull out a pair of shoes for work today (no Imelda Marcos jokes please) that I have not worn for a couple of months. The last time I wore them I can remember them being a little bit tight, hence the reason why they landed in the bottom of the cupboard. I put them on and now I am finding the darned things slipping and sliding all over my feet.
Either an elephant borrowed them when I wasn't looking or I have managed to lose weight off my feet as well...
