The wife wants me to post this as she says it will be appreciated by the ladies.
These are invisible cushions for wearing with heels. Apparently very comfortable and the in thing at the moment. They are £4.99 everywhere, but she found them for £1.99 in Tkmaxx. They had loads near the tills, and apparently they are in their other stores as well, as her sister found them in London also.
