double support phase

The double support phase is a part of walking when both feet are touching the ground at the same time. This occurs at the beginning and end of each step, helping to stabilize and balance the body as one foot lifts and the other supports. It typically lasts a brief moment during each stride, providing a smooth transition from one foot to the other. This phase is essential for maintaining balance, especially when starting to walk, turning, or changing speed, and it varies slightly depending on walking speed and individual gait.
