Frequently Asked Questions
Everything you need to know about your Karhu performance gear.
How do I choose the right size for Karhu running shoes?
Karhu shoes generally run true to size, but for performance running, we recommend a half-size larger than your casual footwear to allow for foot expansion. Please refer to our detailed Size Guide on each product page.
What is the Fulcrum technology in your footwear?
Fulcrum technology is Karhu's proprietary midsole system designed to provide efficient forward momentum, reducing energy loss and keeping your stride balanced and cushioned.
How long does shipping take for domestic orders?
Standard shipping typically takes 3-5 business days. Once your order is processed, you will receive a tracking number via email to monitor your delivery status.
What is your return policy for sports apparel?
We offer a 30-day return policy for all unworn and unwashed items with original tags attached. Please note that for hygiene reasons, socks and undergarments cannot be returned once opened.
Do you offer international shipping?
Yes, Karhu ships to over 50 countries worldwide. International shipping rates and delivery times vary by location and are calculated at checkout.
How should I clean my Karhu sneakers?
We recommend removing the insoles and hand-washing your sneakers with cold water and a mild detergent. Avoid machine washing or drying, as high heat can damage the technical materials.
