Frequently Asked Questions
Everything you need to know about Sidas performance gear.
How do I choose the right size for my Sidas insoles?
We recommend choosing your insoles based on your current shoe size. If you are between sizes, we suggest ordering the larger size and trimming the toe area using your original shoe liner as a template for a perfect fit.
What is the standard shipping time for orders?
Standard shipping typically takes 3-5 business days within the continental US. Express shipping options are available at checkout if you need your gear sooner for an upcoming race or trip.
Can I return my products if they have been used?
We offer a 30-day satisfaction guarantee. If you are not satisfied with the comfort or performance of your Sidas products, you can return them within 30 days of purchase, even if they have been lightly used or trimmed.
Do you offer international shipping?
Yes, Sidas ships to over 50 countries worldwide. International shipping rates and delivery times vary by location and will be calculated automatically during the checkout process.
How should I clean and maintain my heated socks?
To maintain the longevity of your heated socks, remove the batteries and machine wash the socks in a laundry bag at 30°C (86°F). Do not use bleach or fabric softeners, and always air dry.
What payment methods do you accept?
