By the time I headed home I couldn't stand on the left
foot at all, the heel skin has cracks as big as the
grand canyon and with two sores on top up front I just
can't ware a full shoe on it, so will have to use an
ace on it and dig out my cut away shoe I made just for
this kind of deal.

For the heel cracks: Wipe your feet liberally with some sort of ointment
like coconut foot softener, etc, or even just vaseline. Then put plastic
bags over your feet, followed by socks. Wear the socks and plastic bags
24 hours a day for a few days, occasionally adding more ointment. The
cracks will heal quickly.
