It appears your cat's favourite place to lie is right on top of your shoes, but why do they do this? It's apparently due to the fact your shoes carry the scent of you, in turn bringing comfort to your feline - but this is exactly what they want you to think. There's two reasons for this unusual behaviour: 1. Your cat is preventing you from leaving the house any way they can. 2. It's a metaphorical warning for "YOUR SOLE IS MINE".
