How does the Adjustable Flex-Arm work for setting the forward lean angle?

Lower Adjustable Flex-Arm
The Apex Tool

The Adjustable Flex-Arm allows you to adjust the forward lean of your Apex Ski Boot into 4 different forward lean positions: 10°, 12°, 14°, or 16°. A tool to make this adjustment (an Apex hex wrench) is included with each pair of boots. You can also use a hex wrench of your choosing to complete this adjustment. Please view the instructional video here: for further information.

If your boot does not currently have an Adjustable Flex-Arm, you can purchase a pair to retrofit older boot models by contacting us directly at 303-530-3340.
