I'm disabled and have a hard time trying to tie my laces so I bought these to try out and see if I could get them tight enough to hold my shoe on without them being too loose like my regular laces and they work awesomely.  I use a longer shoe horn and have these tight enough to comfortably hold my shoe on and I can slide them right on and off with little effort without them becoming loose or being loose to start with.  Great product.  I'll be adding these to some of my other shoes soon too.
