Well, the typical "try out" approach is to order the same shoe in sizes
9, 9 1/2 and 10, keep one pair and return the other two.

On what planet?

The one we, if not you, live on. I just posted some clothes back to M&S
today ordered on just that basis (not shoes). They even pay the postage.

I find it incredible that anyone could find that less hassle than
simply going back to the shop and getting an immediate refund/exchange.

In my case it's a 60 minute round trip back to the shop or a 30 minute
round trip to the Post Office.

You don't have a suitable inconvenience store closer?

https://www.parcel2go.com/ is a good source for finding one.
