How do I get the best fit for my ThumbShield?

If you are not able to try them on in person, we recommend using the measurement tool available on our website. Carefully read and follow the directions. It is important to print it out with no scaling (this will ensure and accurate size of the template). To accomplish this look for the words “actual size”, no scaling or 100% on the printer properties dialogue box. Make sure you keep both eyes open and can just barely see both lines on either side of the smallest part of your thumb (usually about halfway between the base and the knuckle).

Should I size both thumbs?

Yes, many people have slightly different size thumbs. If your thumbs appear to be different sizes, we suggest buying the smaller size and stretching one out when you get it (by pulling from the inside out). Mark them with an L and R to keep them straight.

Will my ThumbShield stretch over time?

Yes, silicone is not 100% elastic. This means that over time it will stretch out some. This is why we recommend picking the smaller size if you think you are between sizes.

How do I clean ThumbShield?

Silicone is an extremely durable material, you can clean it with soap and warm water, a vinegar and hydrogen peroxide mixture, boiling it water or even steaming it.
