Pretty sure it's a pair of Timberlands. I own a few and the soles + uppers look exactly like that, also the 'tag' on the right shoe (left in the image). You can go to the Timberland official website and customize your own boots for all black soles, leather uppers, tongues and laces for 135GBP. Also, she definitely customized the charm herself, since I can see the wings on the charm of the right boot is actually lopsided. Will post up links to similar charms.
