Elastic Shoelaces...

Who'da thought, no more need to keep cinching up laces... You install these to your shoes and after that you have to use a shoehorn to put your shoes on or take them off but they stay nice and tight...

I was working on my invention to have to never tighten laces again but I discovered these in the meantime...

It used to piss me off when my laces untied. But ya know, it's a good bending exercise and keeps your back in shape.
