Such a shame you can’t buy them in the UK. Tried to get them on prescription but not licenced for use on feet. I have suffered with diabetic neuropathy for 20 years and these are the only things that have helped with the pain. Strange feeling but pain was reduced considerably for 4-5 hours. Do not use them if you have any broken skin or circulation problems though as not recommended for this use. Very impressed but only use them occasionally.
