FAQ

How do I know Protalus insoles will work for me?

Protalus insoles are proven to correct alignment by up to 65% in a laboratory setting, and this leads to pain relief for many customers. Over 95% of those who purchase Protalus insoles keep them beyond the 90 day insole guarantee period and with over 80,000 5-star reviews and with over 1.2 million pairs sold, we believe we can make a difference for you.

If my shoe is between sizes, should I purchase an insole smaller or larger than my shoe's size?

We recommend ordering an insole a half size larger and trimming the insole accordingly.

How long will my Protalus insoles last?

Although our insoles are made of the highest quality materials, over time, constant wear and heat will eventually compress them. Once compressed, you will no longer feel the original comfort or control in alignment. The Protalus ELITE line of insoles lasts up to 1 year. Other models should be replaced every 4-6 months. When performing higher impact activities, they may need to be replaced more frequently.

What is the Protalus 90-Day Insole Guarantee?

We offer a 90-Day Insole Guarantee on all insoles ordered through Protalus.com, excluding Subscription orders. If you would like to return your Protalus insoles, please contact our Customer Service Team for a return shipping label. Return shipping costs are only paid by Protalus for sales that occurred in the United States. If you prefer to ship them yourself please send them to '20750 SW 115th Ave Suite 190, Tualatin, OR 97062' with your order number or packing invoice. If you choose not to use our prepaid return label, we do not refund return shipping cost. After we have received your insoles, we will refund the original form of payment excluding any original shipping cost.

They fit perfectly

These are so helpful. They keep my feet from hurting. I needed the extra arch support you can’t get in basic shoes.
