Regarding today's order cancellations: a promo code was recently given to employees as a one-time use coupon that they could give to one friend or family member to celebrate our 15th anniversary. An error in the system allowed for it to be duplicated & shared today so we had to cancel all orders outside of the intended recipients'. If you received a physical “Crocs 15th Anniversary” special discount card from a friend or family member, please reach out to them for a replacement. We apologize for the inconvenience.
