text: Caused callus on top of my small toes. After wearing them they started squeaking, as most shoes do today.  What happened to quality?  Update:  09.29.15 the heel of this shoe just broke.  I am so upset because the return policy has expired.  I am a professional and only wear this shoe maybe 3 times a week.  JUNK / POOR WORKMANSHIP /  Never would had expected this from a Calvin Klein product.
