Squeaky feet?

No its not the name of an expiremntal indie band or some profound philosophical metaphor. My feet are all squeaky on the Atherstone's wood floor. Does anyone know why? I don’t ever remember my feet making squeaking noises before. I have a suspicion that it has something to do with half healed blisters that are a constant on the balls of my feet. Blisters a side effect of walking 3 miles in humidty along dirt roads in flip flop Anyone else have any ideas?
