Open heel blister treatment using a heel cup

The management of unroofed (open) blisters of the heel include the following steps:
(A) Trim off the roof of the blister.
(B) Cover the base of the blister with a pad designed for that purpose (eg, Spenco 2^nd skin or Band-Aid Advanced Healing Blister).
(C) Make a heel cup out of elastic tape by cutting the corners off a large square piece of tape and cutting through the edges of the tape but leaving an intact central strip.
(D) Apply the tape as shown.
