I believe not, they require a physical photo id then they take it with them into the back to look for your parcel, but they do not scan your id in the front area, however can not say the same for the back area.

If a copy of your ID Is not taken, you can DNA It - the package was mistakenly handed to the wrong person, and there's no evidence that the collection was marked off against your ID.

Is It just the shoes you're planning to SE?

Yes just shoes, will this start an investigation? such as then reviewing cctv ect as this is my local post office.. just being cautious you know. cheers
