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.
I'm doing exactly this. Would you mind sharing some of the other alternatives you discovered?
