Also, try to get double layer socks. I have a few pairs from the Running Room and LOVE them. You can get them for summer and winter, so don't think that the "summer" version would be too hot for Florida. They wick away the moisture, but the double layer also means no blisters! The inner sock stays against your foot, and the outer sock stays against the shoe. So, when you're walking/running, the inner and outer socks rub, not your foot! I started running last March and won't go out without a pair of these socks. They also last a long time (I still haven't needed to throw my first pair out, I only have 2 pairs, and I use them to run 3 times a week), so don't be discouraged by the price.
To be as comfortable as possible, I recommend getting as many wicking articles of clothing as possible. They make some really nice shirts that aren't all that sporty (I have a couple shirts that just look like plain cotton Ts from Under Armour). They make such a difference in comfort...
