text: I do not like these shoes at all. They have made a popping sound in both shoes . It started about 4 months after my purchase . I have either put up with the sound or I don't wear them in public settings . I have called gravity defyer numerous time recently to ask for help or advice , all I get is poor responses and that the rep handling the Amazon account will call you back. I have not gotten a call back and its been a week. I will never buy another pair or any of their shoes .  VERY , VERY DISAPPOINTED IN THEIR FOLLOW  UP AND CUSTOMER CARE .  I give this purchase 1 star .
