The majority of running at OCS, based on the CO's brief before pick-up at OCC-195, is in boots. The running you will do in gofasters is mainly on trails and the like. Before my, spectacularly anticlimactic, NPQ from OCS, we did the first of a few three mile runs through the woods. Plenty of ups and downs, and tree roots, everything.
In short, my vote is Cross-training, you will want the support and ankle protection.

These guys actually do all of the measurements, including measuring your arch. They have you stand on a mat that shows how you stand on your foot. They then recommend a pair of shoes and watch you run on a treadmill. I ended up with a pair of soft arch support Mizuno's that have served me quite well. They got me through OCS. Highly recommended.
I hate to resurrect an old thread but, Im looking to get good running shoes. Do i actually want "running shoes" or the "cross training shoes"? Will you do much off roading at OCS with go-fasters, or are you pretty much using boots at that point.
It's amazing how much bs is involved with running shoes, most of the time the sales kids don't know what they're talking about or jack about running.
Request you expand on what you're saying here. Are you referring to running stores or shoe stores (i.e., Footlocker, Champs, etc.)? I ask simply because I just got a call from Fleet Feet saying that my new trail runners are in:

Well I have some what of a flat foot but I have a little arch.
