I also get the dry cracked heels, but not the bleeding, when they are doing that , you have let them get really bad Nawtee boy.

There are special creams available for this problem,over the counter stuff,but you just have to keep at it, continually,and yes putting the cream on and wearing socks to bed can help.

I also think you should pay a visit to a specialist who does feet, cannot think of the name right now starts with a C though lol, they can shave the area, i have had it done, just moisturise and moisturise till the cows come home,in other words keep at it , keep at it,hopefully you will get some improvement, as they can be very painful when deep cracks appear and bleed, i have had them like that but no more.

Good luck matey.
