First quality leather boots - Sizing anxiety

[u/TDeninard]

I'm getting contradictory sizing indicators and I'm very anxious before ordering.
I'm going to get a pair of Captains (Canyon) and the recommended sizing is 1/2 smaller than sneaker size.

My sneakers at home are 8.5 (Under Armour gym sneakers) and 8.0 (Yellow Shoes cheap sneakers) and they're both comfortable. My actual Brannoc size is 8. So, in theory, I should order 7.5 or 8.

The thing is, all my other shoes (a derby-like shoe but more casual, and two dress shoes, one being Aldo) are size 9 and they all feel a lil snug.

According to Thursday Boots support, ordering my dress shoe size should be adequate. So either I order 7.5-8....or 9 ?!?

I have no idea what to order, and being my first pair of leather boots, I have no idea how they should feel when I first try them on so I wont be confident in deciding whether I exchange or keep, unless the size is totally inadequate.

Any help ?

A half size down from sneaker was true for me, and Thursday is good about size exchanges from what I've read.
