Massachusetts General Laws  CHAPTER 272, Section 98:
   Discrimination in admission to, or treatment in, place of public
   accommodation; punishment; forfeiture; civil right

	Section 98. Whoever makes any distinction, discrimination or
	restriction on account of race, color, religious creed, national
	origin, sex, sexual orientation, which shall not include persons whose
	sexual orientation involves minor children as the sex object, deafness,
	blindness or any physical or mental disability or ancestry relative to
	the admission of any person to, or his treatment in any place of public
	accommodation, resort or amusement, as defined in section ninety-two
	A, or whoever aids or incites such distinction, discrimination or
	restriction, shall be punished by a fine of not more than twenty-five
	hundred dollars or by imprisonment for not more than one year, or
	both, and shall be liable to any person aggrieved thereby  ...
	...  All persons shall have the right to the full and equal
	accommodations, advantages, facilities and privileges of any place
	of public accommodation, resort or amusement subject only to the
	conditions and limitations established by law and applicable to all
	persons. This right is recognized and declared to be a civil right.

A firm personal belief, backed by scientific fact, that bare feet are healthy
and that shoes are destructive to one's physical condition, must be respected
as a type of creed or moral principle.  Individuals so convinced and who adopt
a generally shoeless lifestyle are often referred to as "barefooters".  They
have highly developed situational awareness, and are experienced and adept
with noting and avoiding hazards in any environment that they pass through.

There are no laws or regulations in any state prohibiting bare feet in public
places or establishments, including those that handle food.  The Federal Food
Code contains nothing on the subject, nor does 105 CMR 590 which incorporates
it by reference.  A person who enters such places without shoes has by so
doing already demonstrated his or her acceptable risk level and freely
assumes full responsibility for personal safety and well-being.

Thus, any business establishment should carefully consider the intent of
Massachusetts law before choosing to discriminate against customers/patrons
who prefer not to wear shoes while engaging in good-faith commerce with the
establishment.  Entering a premises barefoot creates no additional liability
burden for the business, does not infringe on any rights of its employees
or other patrons, and effects no risk or harm to property.

For up-front clarity to all customers and employees, retail establishments
could optionally post something like this at their public entranceways:

		 BARE  FEET  WELCOME
		At customer's own risk

This fully indemnifies the establishment against any perceived liability
for foot injuries (not that any exists in the first place), sets expectations
for all parties in advance, and creates additional good will toward the
community.  It is in no manner a health or safety risk, despite common
misconceptions.
