Post Workout Grey Socks out of Adidas

This woman in the video looks like she just came back from a workout, she had her shoes on for a bit until I came back around and saw her shoes off. Her sock was off of her right heel and she stayed like that until about 4 minutes into the video she slides them back on. She uses her feet to crush her shoes(as seen on the pictures) and you get nice shots of her soles. Towards the end of the video, her other sock slides off of her heel, she slides it back on, puts her sneakers back on and leaves.
