Adrián Carratala's Ring to Shoelace

Description:
 
Adrián Carratalá has jealously guarded the secret with which he managed to fool Penn & Teller. Now you too can amaze your audience with this miracle!

Effect: A borrowed ring disappears under a handkerchief and immediately appears tied to the magician's shoelace.

And this is the best of all:
The magician never approaches the shoe.
It doesn't depend on clothing. It could be presented completely naked (only with shoes, of course).
The gimmick is installed in 5 seconds, and the routine resets in another 5 seconds.
The entire system is self-contained and fits in a pocket.
No duplicate rings are used. The ring held by the spectator is their genuine ring.
There are no steals or suspicious movements; hands are shown empty at all times.
No reels, threads, or elastic are used. The gimmick is designed for professional use.
Each unit has been handcrafted in Spain with great care and supervised one-by-one by Adrián.

Important: The use of dark shoes and/or with black laces is recommended.

Inspired by an original idea by Richard Sanders.
