If you fall out of OCS humps you are not going to have a good time. However, humps are pass/fail so you need only survive them. MADarmstrong is right that it is a good idea to run in boots (especially for seniors). You will rarely run in go fasters at OCS--I think only durring individual runs, squad runs, and PFT's (total of about 5 times). The rest of the time you will RUN in boots and utilities at the very least and boots and utilties, kevlar, weapon, 782 gear, and two full canteens at the worst. As long as you're not some skinny little guy you should be able to handle the weight reasonably well. We had this guy in my company who was about 5'5" and 120lbs that could run a sub 15min 3 mile but when you put gear on him he was doing around 22min--this is fast but it shows how much the gear can slow you down when you're small.
