Frequently asked questions
How does the custom fitting process work?
You pick a device, select a few measurements from guided dropdowns after measuring your hand, and upload a photo or short video. The system uses that information to generate a parametric 3D model sized to the customer.
Do I need to download an app?
No. The full intake experience happens in the browser on a phone or computer, which keeps the process lighter and easier for first-time buyers.
How long does production take?
Production typically takes 3 to 7 business days, then the order ships after it is printed and prepared.
What happens if it does not fit?
Custom Fit Grip offers a remake or support policy for fit issues to help you feel confident placing an order.
Are the comfort accessories medical devices?
No. These are comfort and independence accessories, not medical or therapeutic devices.
