I buy shimano size 46, how do Lake shoes compare? The same/bigger/smaller?

Looking at some BNIB shoes on a certain internet auction site but have never tried any lake shoes & am not rushing over to a LBS just to try em out & buy online…

PS. I have tried google without much luck

standard size for mine I wear 44 they are 44 as are my Shimano ones
I seem to recall some say they are narrow??? I might be misremembering that though and mine dont feel narrow

Dunno about shimano shoes but I normally take a size 45 in ornery shoes and summer Sidis, and 46 in winter boots including Lake MX146s. There’s room for thick socks and liners in there.
The std fitting may be narrow but they do a wide fitting for those of us blessed with flippers.
Halfords have the 303s on sale at £159 at the moment. Click and collect, pay on collection.

Cheers Sub, the Halford option is worth noting. Seller has offered me the option of trying them and isn’t hundreds of miles away, so that will simply be my best option.
Just wondering if I was barking up the wrong tree
