FAQ
Shipping, sizing, returns, and order support.
How much is shipping, and how long does it take?
Standard shipping to the US and Canada is $9.90 and is estimated to arrive in 5–7 business days from the order date. Expedited shipping is $13.99 and is estimated to arrive in 3–5 business days. Orders of $99 or more receive free standard shipping.
How do 30-day easy returns work?
Contact us within 30 days of receiving your order to request a return. Items must be unworn, undamaged, and returned in their original packaging. Return shipping costs may apply. Email service@kalvron.com for return instructions before sending anything back.
How should I choose a size?
Use the size options shown on each product page because availability and fit vary by style. For the Air Max 90, US men’s sizes 5–15 are available; open Overview on the product page for the full US/EU/foot-length chart. Measure both feet and use the longer measurement. If you fall between sizes, choose the larger size. For help before ordering, email service@kalvron.com.
Can I change or cancel an order?
Email service@kalvron.com as soon as possible. We will try to help before processing begins, but changes and cancellations cannot be guaranteed once an order is underway.
Where can I find material and feature details?
Materials, construction, and features vary by product. The information on each product page applies to that specific style. Contact us if you would like to confirm a detail before ordering.
