FAQ

How can I choose the right product?

You may first want to confirm whether your pain is mainly in the carpometacarpal joint (CMC). We have prepared a self-test method for you on the service page. However, it may be more accurate if your healthcare provider can help you determine it. Then, you need to choose the product that fits your palm size according to the size chart. We have three sizes for you to choose from: large, medium and small. Then you can choose the color you like. Finally, don't forget to choose your left or right hand.

How can I get support if I am not good at using the product?

It is best to read the product details page for instructions on how to use the product. If you still have questions, you can contact our support team via email: support@fortemotus.com

Is the fabric latex-free and gentle enough for sensitive skin?


All our supports are crafted from latex-free breathable composite fabric. The hypoallergenic, sweat-wicking material reduces itching or redness for sensitive skin, safe for those with latex sensitivities.

Is this thumb support suitable for frequent hand use from daily chores & repetitive work?


Yes. The integrated thumb-wrist structure stabilizes the base of your thumb to cut down repeated pulling and strain during daily hand movements, bringing a gentler experience for heavy hand usage.
