You should expect it to be delivered on Tuesday. Monday is the Memorial Day holiday.

The thing to consider is this. Priority Mail averages 2-3 days for delivery. Just because you ordered your shoes on Friday morning, that would not mean that they were shipped on Friday.

You would need to check with the seller to determine when the package was shipped.
