I had a look on UK Amazon and couldn’t find the exact one, but found this which seems to combine the padding with a little toe separation and correction. Will give that a try, and look at Bunion Sleeve options similar to yours as well if it ends up feeling a bit flimsy.

When I joined this forum I never imagined that I would end up asking someone to DM me a picture of their feet, but yes please - go ahead, would be interesting to see.
The other question I’d have is - has the actual inward curl of the toe been corrected at all by wearing the sleeve, or is the treatment entirely just about protecting it?
