I second giving up "fashionable" shoes. We have gone in Sept & Oct, and each time I have brought a comfortable pair of tennis shoes. The first trip I wore my normal socks the first part of the trip. After several days I started developing a couple blisters. I switched to some think moisture wicking socks the next day. While those helped a bit, I opted to wear my thicker moisture wicking socks the next day. When we got back to our room that night, there wasn't a sign of a blister! I had been hesitant wearing the thicker socks in FL in September, but I wore them for the rest of the trip and did not have any blister issues after that. I wore the same socks on the next trip, and did not have any blisters. I will be taking the same kinds of socks on our next trip.
