FootReviver cracked heel cream daily (or twice a day) and wear closed heel shoes with cotton or wool socks for a few days until it improves. Flip flops and open backed sandals make it worse as they allow the heel to spread.
As per a previous thread in which I asked for advice, I can’t recommend Footreviver enough. I have been out twice in my new boots with new insoles and the improvement on my previous pair was fairly significant.
