Our shipping carriers (USPS & UPS) work independently from Atreyu Running Company, therefore we are not responsible for any lost or stolen packages.  That being said, if your package goes missing, we recommend these steps:  1. Hang tight. It is possible that your package was pre-scanned by the carrier prior to delivery. We suggest waiting an additional 1-2 business days for the package to arrive before filing a claim.  2. Personally file a claim with the carrier in question - USPS or UPS.  3. Reach out to our athlete experience team at support@atreyurunning.com. They are available to help you throughout the process.  Learn more here
