Having experienced the excruciating pain of an ankle injury while in the backcountry, we now wear the heavier hiking boots with adequate ankle support. Should you be prone to such an injury, you may also want to consider wearing an ankle support or brace as well. Knee supports are also recommended, especially when hiking moderate and strenuous trails. Downhill hiking for any long periods of time is extremely hard on the knees.
Hiking with trekking poles, sticks, or staffs will also help negotiate trails and help against injury. Consulting with a therapist or orthopedic doctor for available devices and or strengthening exercises may also reduce the chances of an injury.
