As a company, we have experienced this issue quite often, so it is important to provide clarity.
Our factory has mis-labeled the U.S. size on our size labels--this is why you will find a note on your packing slip stating to pay no attention to it because it's invalid and incorrect.
To begin, here is a link to our footwear size chart: https://www.rockdeep.com/pages/size-chart
It is referenced on our footwear size chart on our website, and it has been articulated by our CEO numerous times that we use the Euro size to ensure our customers get the most accurate fit when sending them shoes.
Here is an excerpt that can be found on the link above:
"True to size is an ambiguous term when speaking to anyone at any brand. This is because each brand uses different tooling(outsoles) for their footwear. However, they all use the same Euro sizing when adjusting their sizes to U.S. sizing. "
We recommend that folks check the Euro size on a pair of shoes at home, then compare it to our footwear size chart on our website, then match it to the corresponding U.S. size chart.
.Even though you will be clicking on a U.S. size, cross-checking the Euro size with the U.S. size ensures that you will choose the correct size and that there is less of a chance you will have to go through the exchange/return process.
PLEASE NOTE:
Going by the Euro size does not mean we ignored your size request. It does not mean we sent you the incorrect size. It does not mean we made an error. In fact, the Euro number is more for the staff to ensure they are pulling the correct shoe for you.
Please do not email us telling us we have to be responsible for your return label because we made the error--or that you wish someone would have told you before that we use the Euro size. Please refer to our return policy for return label instructions.
