what is the size of your feet? Why idoes it change when you're tired?

i dont knkow exactly but may i ask.. are you sending me some pair of shoes??? hehehe.. i never knew that!! maybe because the muscles tend to relax..

I am a size 5 1/2. No I have never noticed it shrinks when I'm tired or just gets out of my shoe but some days I notice that my shoes are really lose and the next kind of tight I used to think it was just because of wearing different socks but I wear the same kind of sock everyday now and the same thing happens. I think its weird. Maybe I am tired the days they are smaller I'll have to pay attention to that the next time
