Shoelaces are something of a “thing” for me. I had searched for years for just the right way to tie them that would
a. prevent them coming untied and yet
b. was quick and easy to tie and untie.
For the past seven years, I have used a method that has accomplished that for me, and have added lacing techniques that allow me to also “custom fit” shoes when foot problems of various kinds temporarily arise, as well.
