I suppose they're useful if you get frost frequently in order to protect ceramic pots from freezing solid. We don't use them in Greece either but it's rarely frosty for long.
A cheap easy option would be hard plastic washers (PTFE/Teflon or Nylon) as used in plumbing. They are available in various diameters and thicknesses from places like B&Q, Screwfix and only costing a few pence each. Something like 10 or 20mm x 3 or 5mm should be ok for most pots but obviously you can get them in larger or smaller size to suit your pots.
I’ve never used these for any of my pots, ceramic glazed or terracotta, do they really do anything? I never understood how they stop a pot freezing or becoming waterlogged? I’m not saying they don’t work, genuinely curious. Although I wouldn’t have thought they would stop woodlice and ants if they really wanted to get into your pot.
Maybe I’ve just been lucky with my pots 🤔

On a hard surface in relentless rain, it's easier for them to sit in water if it can't drain away easily. If you're in a drier area, or the pots are on gravel, it's not really a problem. They wouldn't stop a pot freezing. I'm not sure why anyone would think they do that. They wouldn't stop any insect getting into a pot either. They just crawl up the outside via the feet. I use offcuts of timber battens etc. I've even used bottle tops.

Thanks @Fairygirl, that makes sense re the water logging if where they sit has some standing water in bad weather

Apparently you can spend a pretty penny on pot feet… £21.99 at https://www.jardinopia.com/antique-bronze-french-bulldog-set-of-3/ (and many more designs).
Very cheap from builders' merchants
