Hello!
The itching of foot is due to use of faulty foot wear, excessive sweating, contact dermatitis, allergy, drug reaction, fungal infection, athletes foot, Diabetes or other metabolic conditions.
I would suggest you to tell your friend to get her feet examined and take necessary precautions.
Tell her to use a good moisturizer during winter and not to keep her feet dry.
Take care!
