Foot blisters from boxing

Hi, I just started boxing again and paying for lessions.. Well tonight was my first night back in a couple of years. And After a good hard session I got foot blisters.. Now I dont want to be a pussbag and cancel tomorrow session. Is there anything I can do to help with the blisters.. They prob wont be afactor, but I want to be 100% tomorrow

im'a give this a bump cause im starting Maui Tia tomorrow...and we go barefoot on a hardwood floor....soooo carry on..
