Hi! Now, I agree with the above, stop soaking them evernight.
There are three things you need to do, i have even enclosed a youtube clip to demonstrate..PLEASE fast foward it to 7.13 as that is where the below is illustrated.

a) get something with BETA HYDROXY ACID - in it. Apply over your feet. This is a chemical exfoliant. Now when I say chemical don't be alarmed, it is one of the most researched ingredients in Skin care, with ample scientific research proving its benefits.
BHA is oil-soluble and can penetrate into the pore exfoliating accumulated skin cells that clog pores and can also exfoliate on the surface of skin as well. It is best for skin types prone to blackheads and blemishes Apply to your heels - not a lot just a small amount, every night and then put some thickly emollient moisturiser 10 min after you have applied the BHA product.
b) Something SUPER emollient such as a coco butter or shea butter moisturiser, something like palmers coco or shea butter.
Put socks on and let it sink in overnight. Do this every night for 1-2 weeks. You will DEFINATELY see a HUGE difference. Now, from here on out you can continue to use the BHA every second or third night just to keep the dead and dry skin cells from forming but it is not neccessary to use MOISTURISER each night. You can if you want to. It will benefit you - YOu will notice
c) keep a pedi file somewhere, and 2-3 times a week or as often as you feel necessary, FILE OFF the dead skin on the heel.
It is lengthy, but essentially you need a BHA, pedi file and shea/coco butter. You wil never have cracked heels again.
Hope this helps
