My Luxman turntable footers are a multi-product combination.
I use Herbie’s Grungebuster dots with two-sided adhesive...

on the underside, exactly where the stock footers have been removed.
The receptor socket for the cone point sits perfectly in the top of an Aurios Media Bearing.
Aurios is out of business, so you can watch on Audiogon and Ebay for used sets. You need four. Using a bearing under the turntable is a big part of how to advance the sound of the turntable by abandoning the factory feet.
I’ve never done so, because i don’t like how it looks. I like The Stillpoints, but they are way out of my budget for feet, so i’m fine with Luxman stock feet. Maybe i should try my AT-636 pneumatic insulators, but i think aesthetically it's bad idea for PD444 (which is the best design among the vintage turntables, imo)
