Whatever works for you is great. Just make sure you break them in, and run in them several times before heading off to SWAB summer. Also, shoe manufacturers like Nike and New Balance recommend throwing out shoes after 300-400 miles of running. I don't necessarily find this to be true, but follow common sense. If your feet start hurting, you should order new shoes.
Also, if you are unsure, you can visit a nearby store specializing in running shoes. Just be careful, in all likelihood you do not need a very expensive pair of shoes and they may try to sell them to you (~ $70+).

Research at Harvard has been
suggesting that cushioned running shoes have been harming our bodies more than protecting them. That is the chief reason why I switched to minimalist/BF running (takes a while though). That's right, I run in those things!
