This is a basic gravity boot tie that I use for self-suspension (and partnered suspension). I learned this a long time ago in a peer sharing context and I'm afraid I do not know who invented it or specifically who I learned it from, apologies for the lack of crediting.
You can learn lots more about self-suspension on this web site: selfsuspend.com
This video is intended only to supplement appropriate in-person instruction! I learned a basic gravity boot years ago, and I'm afraid I can't recall who I learned it from, otherwise I would credit them here! I know I have modified it since then. There are numerous versions of this tie that are fairly widely taught. For more self-suspension content, check out selfsuspend.com!
