I always but always ride with my toes on the pegs and it's second nature to move my feet around as and when appropriate. In the dry I rarely use the back brake anyway so little right foot movement needed. I wonder what your body position is generally - it shouldn't be cumbersome to move around a bit, are you sitting bolt upright or are you holding the bars in a vice grip? Maybe I read too much into this, but if your feet can't move easily then you might need to relax more on the bike generally.
