Good idea here with the low angle of view. A paneled crop would eliminate all the foreground, to isolate your subject. You could also play with the angles of the shoes to see if there were other compositions that had more of a wow factor.
I think the foreground blur is a little too much. Perhaps cropping of sightly would have helped to be less distracting.
Also, there's a harsh shadow cast on the wall. I like the concept of this, however.
