Frequently Asked Questions
Everything you need to know about Karhu performance footwear and gear.
How do I determine the correct size for Karhu running shoes?
Karhu shoes typically fit true to size, but we recommend checking our specific size guide for each model. If you are between sizes, we suggest sizing up by half a size to allow for natural foot expansion during long runs.
What is the standard shipping timeframe for orders?
Orders are typically processed within 1-2 business days. Domestic shipping usually takes 3-5 business days, while international delivery can take 7-14 business days depending on the destination.
What is your return policy for performance gear?
We offer a 30-day return policy for all items in original, unworn condition with tags attached. Please note that for hygiene reasons, socks and undergarments cannot be returned once opened.
Do Karhu shoes feature specific technology for overpronation?
Yes, many of our models utilize our patented Fulcrum technology, which is designed to provide balanced cushioning and support to help guide the foot through the natural gait cycle.
Which payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, American Express), PayPal, and Apple Pay. We also offer flexible financing options through Klarna in select regions.
How should I clean and maintain my Karhu sneakers?
To preserve the technical materials, we recommend hand washing with a damp cloth and mild soap. Avoid machine washing or drying, as high heat can damage the structural integrity of the midsole.
