In the video, a man is seen holding a shoe and a red and yellow insole. He is wearing a black shirt with the words "TRAILRUNNING Review" written on it. The man is demonstrating how to insert the insole into the shoe. He first shows the flexibility of the insole by bending it, then proceeds to place it into the shoe. He adjusts the insole to ensure a proper fit and then secures it in place. The man appears to be speaking throughout the video, likely providing instructions or commentary on the process. The background of the video is a blurred image of a mountain, suggesting that the video may be related to outdoor or trail running activities.
