If there is a good reason, you can return it, such as wearing too small. By the way, you must also have a receipt.

Refunds can be made within the validity period promised by the merchant, provided of course that the shoes are not damaged due to personal factors.

The most important thing is how to communicate the merchant's service attitude and my return attitude. Discuss with the other party that if the product does not have major defects, you may have to pay for the round-trip shipping costs yourself. Otherwise, you will not be able to do it, and they will not agree to it. You have to understand this.
