As a diabetic, I have to take excellent care of my feet. I had severe cracked heels and have tried every product I could find on them. Blue Goo has turned out to work the best of all of them. It is much more cost effective also, as you are required to use less of it, as well as the pricing being lower than all the others. My heels look and feel normal; all evidence of the cracking is gone. I highly recommend this product to anyone who wishes to rid themselves of unsightly and painful cracked heels. Works wonderfully on elbows and chapped hands, too!
