What type of shoe should i get?

I'm going to florida and am going to be doing a lot of walking. I own a couple pairs of shoes which i could bring now, but i want to buy something else. I am looking for a specific type of show which is comfortable for a lot of walking. I own a couple pairs of jordans and nikes now, but am willing to get more. I will be wearing cargo shorts and a tee-shirt most of the time.
