How do you all suppose that "pointed cap" might look with just a touch of broguing...?
One thing to consider. If a manufacturer doesn't have a pattern for something--say a pointed toe cap--it's possible that they would make a new pattern for you, but also possible that they would slightly mess up the proportions. It's unlikely that they would nail it on the first try, and also unlikely that they would make multiple prototypes for a one-off boot order. I'd look for examples online and if they've already made it say, "make it like this" or ask if they have any examples they can show you that you could approve of. I know that a cap toe that's a little too long or a little too short can really mess up the way a shoe looks.
Another thing to think about is how the shell rolls. Mine crease right behind the cap and it looks good. If the cap extended back farther, would the rolls develop better? Worse? I don't know, but something else to consider.
