Many people find it hard to bend down to put on shoes. One has to bend down to (1) hold onto the tongue and (2) put in the shoe horn.
True, if the shoes have no laces, sometimes one can get away without holding onto the tongue. Also true, if the laces are very lose and the tongue is very stiff and pointing upwards one can just use a shoe horn.
But for all those other situations, one needs something the extends to hold the tongue and a long shoe horn.
This is what I created in the ShoeLeash™. You can hold onto the tongue from far away AND use a shoe horn at the same time.
I demonstrate it on ShoeLeash.com.
It is a new invention so there is no economy of scale, sorry about that. In a few years, it will be somewhat less expensive.
