Dry feet

I moisturise my feet and legs every night too. But I use regular moisturisers such as Nivea or Vaseline body lotion. Maybe you need a more specialised lotion for especially dry skin. As you say your skin looks shiny, is there any chance you have got water retention?

I was given some sanctuary spa heel balm as a gift and it is brilliant

Flexitol foot products are excellent especially the foot balm and the heel balm. I think ordinary Nivea etc moisturizers aren't powerful enough for the feet.

Buttonjugs I use a scholl electronic hard skin remover on my feet. When I had jaundice in 2017 the skin on my feet went very dry and was told by a dermatologist to use Dermol 500 lotion everyday . Jaundice does terrible things to your whole skin and bladder and bowels .

I had Dermal double gel to wash in.until my skin when back to normal. Using the scholl electronic hard skin remover and the Dermol 500 lotion pieces of the hard skin came off in chunks. Gross I know. But because of using the cream had lovely pink skin underneath. Since then use it regularly even on my face my skin has never been in such good condition . The 500 lotion comes in a pump bottle so it's economical. Even though I get mine on prescription. It's soon absorbs in none greasy and fragrance free.

I've always had really dry touchy skin .
I have to moisturise it after a bath .
The best product that I've tried is Oilatum or Boots cheaper copy of it .
The only draw back -it can make your bath or shower tray like an ice rink afterwards .

Maddy suggests that you might have water retention - why don't go check with your GP first ?
And he or she might be able to prescribe creams on prescription for you .

Otherwise oral vitamin E might be beneficial .

It can be associated with peripheral artery disease which won't improve until the blood flow is better... maybe check it out with your GP?
