It doesn't have to be perfect. I wouldn't say over one inch, and even then it's pushing the boundaries. Ideally, it shouldn't hang over half an inch to three fourths of an inch. You could try ducking your stance more to fit your entire foot on, but if it's uncomfortable, don't bother, also depending on your height you could widen the stance as long as it's comfortable. Anyway to either look at the board and put your boots on it, or find another board with the same waist and check it that way at a local retailer?
