Contour mouse is designed to support your hand comfortably without the need to clutch the mouse to control it. Excessive clutching and finger flexing can aggravate the hand and wrist resulting in repetitive strain injuries. A pronounced arch on the top of the mouse gives your hand support from underneath. The specifically designed arch fills the hollow of your palm and allows you to rest your hand on top of the mouse. This promotes straight alignment of your hand and wrist while slightly elevating your wrist from the desk. Elongated buttons allow you to use the second knuckle of your finger to activate clicks which uses a stronger, thicker tendon. Contour Mouse allows you to rest your hand on top of the mouse and click buttons with small, subtle motions without flexing your fingers.
The seventeen degree pronation angle relieves pressure on the forearm while still minimizing grip force. This angle, in comparison to a more vertical angle, was concluded to be the perfect balance of ergonomics and productivity.
To top off the comfort you gain from this mouse, we've also made a variety of mouse sizes available to you for both left and right handed users. Your hand should be able to rest upon the Contour Mouse and support your full palm from underneath. To find your perfect size, you should measure the length from the tip of the middle finger to the first crease of the wrist. See the table below to find out which model size is best for you.
