Co-worker hygiene issues

PLEASE HELP ME AND DONT JUDGE ... Coworker is MORBIDLY obese. As such, I think it's hard for her to physically maintain good hygiene. During the summer her body odor is TERRIBLE, hair is always greasy, leaves behind sticky smears at the stations she works at but the WORST part is her feet. She wears flipflops all year long as she admittedly struggles with putting on most other shoes due to her size. Her feet have absolute LAYERS of dead skin and warts!! I cannot be the only one who finds this unprofessional and straight up gross??

Management are being WUSSES about addressing it.

God forgive me but sharing space and air with this person can be straight up GROSS.

How to proceed??
