if anyone has rough heels (I do since I'm always barefooted)
Urea cream is excellent for a fix.

I had some that was 40% but recently got a jar that is 60%.
Just rub it on your feet at night (won't stain sheets)
To keep it on your heels you can get these cheap stretchy heel socks that have a silicone molded heel inside.

This keeps the cream on all night and literally the next day you can feel the difference.
My problem is being able to reach my heels since titanium knees don't have the bending range like a natural one
