If you encounter any structural defects—such as premature seam separation, knitting irregularities, or structural flaws—within 30 days of receipt, we will replace the item free of charge.

Simply email info@seoulinsocks.com with your order number and clear photos of the issue.

*Please note: Our guarantee covers manufacturing defects and does not apply to standard wear and tear or improper washing/care.

Our guarantee covers 30 days from delivery. Because premium socks are daily apparel subject to surface friction and routine laundering, natural fiber wear over long periods is expected, and extended warranties are not offered beyond this timeframe.

We want you completely confident in your purchase. You may return unworn, unwashed items in their original, undamaged packaging with all tags attached within 30 days of delivery for a full refund.

To initiate a return:

1. Email info@seoulinsocks.com with your order number and reason for the return.
2. Our team will provide return instructions and our California fulfillment center return address (14555 Valley View Ave #B, Santa Fe Springs, CA 90638).
3. Pack and mail the items securely using a trackable shipping carrier. Customers are responsible for return shipping costs.

Once received and verified by our warehouse team, refunds are issued within 5–10 business days back to your original payment method.

Due to strict health and sanitation regulations, socks that have been worn, washed, tried on against bare skin, or removed from original packaging tags cannot be returned. Gift cards and final-sale promotional items are also non-refundable. If your items arrived damaged out of the box, please reach out via our Craftsmanship Guarantee process.

Return postage is the responsibility of the customer. Original outbound shipping charges are non-refundable. We advise using a tracked shipping method to prevent lost returns.

Refunds are processed within 5–10 business days after inspection at our facility. You will receive an automated confirmation email once credited. It may take an additional billing cycle for your banking institution to reflect the funds on your statement.
