LOL! I usually put it on before bed. Otherwise, I put on socks and there is no sliding. Though you have to be careful which kind of moisturiser you use as I have ruined a pair of socks using paw paw. I just can't get the grease out.
This one of those Catch-22 situations. As a diabetic, I have to keep my feet dry but not allow them to crack and become a target for infection. I tend to use glycerine and/or coconut oil but never between my toes as per instructions for my diabetes classes. I do this before bed and put socks on. Glycerine is amazing albeit a bit sticky.
It's something to do with diabetic skin being susceptible to infection and ulcers. Even a band aid can damage diabetic skin. Mine is still quite robust but if you get into the habit of doing the right thing . . . you know, an ounce of prevention - especially as diabetes leads to having no feeling in your feet. In my whole class of people I was the only one who dries between my toes after a shower. The educators were very shocked. Diabetics need to educate themselves.
Ps . . Vee, in my classes, one of the lecturers told us about a man who had a toy car wedged in the back of his foot . . . he could not feel it and it had ulcerated and he was on the verge of gangrene. Scary.
