Bringing merch as a carry on

Hoping to buy a couple pairs of shoes during my trip this week.

On the plane (delta) I would normally just have my backpack (personal item). Would it be fine to have my ”carry on“ be a merch bag with 2x shoe boxes, store that in the overhead, and keep the backpack at my feet? I don’t see why not but also want to see what y’all have to say.

Thanks.
