Re the slippage ... if the shoe feels loose around the heel when you are not stepping and having the slippage, then it's not the right fit. If the shoe fits well stationary, and there is a little bit of slippage, then you are probably okay ... just dealing with a very stiff sole that will soften a bit over time & use.
On the scrunching over the toes ... if you mean that the leather looks creased, that's going to be with you all the time & is fine ... to be expected. If you mean that the creases in the leather are causing you discomfort, then that's not good and while it may diminish or even go away with time, it's not an ideal starting point.
Be there or be square. Only I can do both!
