According to dancestore.com (Everything for Swing):
A Balmoral (or “Bal”) refers to the way an Oxford style shoe ties up. A Bal is far less adjustable than a Blucher because the bottom of the lace-up part of the shoe is sewn down, so the part of the shoe around the ball of the foot can only be one circumference and cannot be adjusted smaller or larger.
Because of the lesser adjustability of a Bal, it is not as easy to fit people with narrow or wide feet.
When properly tied, only the tip of the shoe’s tongue can be seen on a Balmoral. (see Oxford)
“Balmoral” refers to the castle in England of the same name and comes from Prince Albert taking an extended holiday at the castle in the mid 1800’s while wearing a pair of boots made for him that had this type of construction for the lacing.
