The site that comes to mind is Ian’s Shoelace Website. The ultimate guide about shoelaces. The most impactful/important thing for me was Ian’s Knot, the fastest and most correct way to tie a shoe. I discovered this website in the mid-2000s and have been using his method since. Anyway, it’s a fun and comprehensive website about shoelaces. https://www.fieggen.com/shoelace/ianknot.htm
