hey guys, I'm a newbie at airsoft and am looking to play for the first time some time during late December/January time frame. We are getting a group of guys together for some fun. My question is on shoes. Since we are just a bunch of guys hacking around (nothing serious yet) then would tennis shoes be a problem? I know a couple guys that already have boots, but I simply don't have it in the budget yet for boots. Are tennis shoes ok for a skirmish?
