Is it worth getting new shoes when your feet are still sore?

I have worn through another pair of shoes. That's what I get for walking 18,000 steps a day. Curse you Vivofit! My feet are blistered in some areas. Calloused and dry heeled. I need a new pair but was wondering whether it was a good idea to let my feet heal up first. Any new shoe might be uncomfortable once my feet are well if I get it them now...
