Sorry if this has already been mentioned before and I'm repeating somebody else's recommendations (too many posts to trawl through) - I think the main point about moisturising own feet is not to keep them moist (bad idea as stated above) but so you get to know the look and feel of them so you'll be more likely to know if they/your skin starts changing for the worse.
@Toffer, Hi
No, I don't think this aspect of applying cream to feet has been mentioned. I can appreciate what you are saying and, yes, it is important to be aware of any issues with your feet.
However, I am under the impression that the use of a moisturizer to feet, for diabetics, is actually to help keep the skin in the best possible condition as all diabetics are at greater risk of problems so the healthier the skin, the less likely to have problems.
Using a moisturizer doesn't mean plastering it on and leaving your feet covered in a layer of cream. Yes, that would mean leaving your feet 'wet'. I believe it's essential to use only a small amount of moisturizer, massage it into the skin thoroughly until it is drying off. During this massage, it's a good time to check your feet are warm to the touch and that you can feel your touch. If in doubt, seek professional advice, of course. If you are able, it's also a good time to check the pulses (plural) in your feet.
Hopefully, that makes sense and that you are not leaving your feet in a state of layers of cream
