to be honest, it really depends on entirety of your build - especially size of your upper legs. the height and wt guidelines of manufacturer are probably pretty close, which I posted below. i fit in their guidelines but my feet are 10.5 and they are not tight on my feet.
only way to know is to try them on. i see you are in fullerton and i'm in SD so that's not really practical. sorry. you could go to Bass Pro Shops or similar store and try on a few brands to see how you fit. you definitely want them to fit right - if you're not comfortable it defeats the whole purpose.
