Yes, your question makes perfect sense. Here are a couple of thoughts:
First, my favorite sock pattern says simply to knit the foot section until you're 2 inches shy of the total length of the foot when the foot is being stood on. For example, if the foot is 11 inches long, you'd knit for 9 inches, then start decreasing for the toes.
Second, I'd stick with the pattern/same number of stitches - but go up to the next size larger sock needles. Say your pattern calls for size 2 needles - I'd go for size 3. This way, your foot part would be a tad wider, in addition to being the right length. This part seems to be optional, in my experience. But it's something that could well help. There really is quite a difference between a man's size 11 and a ladies' size 6 1/2.
