If you like this sort of thing check out Ian’s Shoelace Site, has hundreds of examples of this sort of thing for every scenario possible.

I usually go with Train Track, but I’ve had to replace my laces recently while away and could only get ones that were too thick to double up in the eyelets so reverted to Ladder.
I find these very similar in feel to the straight methods but you can get them much tighter. Also depending on the shoes you can hide the verticals for the train track method behind the eyelets which has a distinctive look.
