Walking is a combination of both conscious and subconscious actions. While walking, you are aware that you are moving your body to get from one place to another, which requires conscious decision making and planning. However, the actual movements of walking, such as placing one foot in front of the other and maintaining balance, are often automatic and don't require a lot of thought or attention. This is similar to how driving a car or riding a bike can become automatic over time, with many of the actions requiring less conscious effort as they become ingrained in muscle memory.
