Maybe he has a retractable blade hidden in one of the shoes. He could fit a 6-inch blade in there. Perhaps if he clicks his heel it'll spring out and he could use it as a weapon. Not a bad idea actually. Just have to be careful of accidentally flipping it out 
I think you might have watched a little too much James Bond films.

I agree. Terrible shoes.
And I am not a fan of the ankle showing trousers either.
