I have recently purchased a cold compress which has worked really well at cooling my feet down, especially at bed time - it is rectangular in shape so keeps falling off, so my mind started working overtime - wouldnt it be nice to put your feet into a sock-like cold compress - I have googled this but cant seem to see such a product on the market. Has anyone seen anything like this and if so where can I lay my hands on them (or I should have said my feet)
