I learned a few knots and even now when I buy a new pair of shoes I consult the site to see what lacing style would suit the shoe and my foot. (since different styles put different tension on the wearers foot).
I have to say, I'm happy it exists, it enriched my life in such a subtle way, this is the kind of content that the internet was made for in my opinion.
If you really want the full dress boot option and are prepared to spend a lot, there's always RM Williams[2] of course. However, I've heard reports their quality has suffered in recent years. I have three pairs of Yearling Craftsman boots now between 15-25 years old. They've all been re-soled multiple times and the older ones are looking a bit worse for wear, but I've certainly had my money's worth out of them.
