I used a kind of rubber foam usually used by children for crafting:
Spoiler:
A standard hole puncher has just the right diameter for the cherry mx switches.
I cut them about 12mm x 12mm which fits very well.
The end result is fairly nice for 5 bucks and I only used a fraction of one of the 10 sheets in the pack. Bottoming out is noticeably quieter but I don't think the switch travel is changed much.

It'd be nice if you could compare them with actual landing pad.
Well not really. The only option seems to be a mix of diameters. Which means you have no idea how many packs you have to order to get the 87-100+ rings you need for a keyboard. If you could order specific sizes then it would be cheap.
