Keeping time with your Foot

I have been playing for sometime, but am now having to focus on timing as I am playing with others. I play a banjo and the as the speed of my rolls increase so does my foot tapping. How do I train myself to keep a constant pace (timing) with my foot while my fingers are speeding along. I have tried an in the ear metronome, but I think I am a more visual person when it comes to sensing rythym. Does anyone have some experience with this problem that could help me??
