Chastity and orgasm denial discussion

Hello everyone, I’m looking to purchase an item I saw on-line several years ago and now for the life of me can’t find! They are restraints that lock the wearer’s stilettos onto their feet. I’ve found a similar item in leather but what I’m really after are the metal chain ones. Does anyone know where these might be found? Do they really exist? Or did I just dream them up in my kinky little mind? LOL! Thanks for any help you might have! humble and fond regards, maid madeleine P.S. The chains wrap around the top of the foot and beneath the sole of the shoes (in between the toes and the heel) and connect to a chain which wraps around the ankle. Properly secured with a lock there is no way to remove your high heels without using bolt-cutters to snip the steel chain. I love this idea! mm xo
