I was wondering if anyone could give me some sizing advice on the 4497 last? I am a US 9D on the Brannock. I wear TTS on most Alden lasts, 8.5D on the Barrie last, and 8D on the Trubalance last. For some of the English brands I have worn, I am an 8E in John Lobb, an 8E in George Cleverley RTW, and an 8.5E in Gaziano & Girling.
If you go through this thread, you'll notice that most size down 1 full size from their US size to their UK Tricker's size, both in the 4497 and 4444 lasts. Imo, this is due to the fact that they wear them tighter and/or with thinner socks than they're intended to. Fwiw, Tricker's considers only .5 difference between US/UK sizes. Richard (Shoehealer) has confirmed this. With that in mind, the 4444 is said to be .5 large, so you'd size down 1 full size US/UK in that last.
I'm also a 9D on the Brannock, 8.5D Barrie, 9D Plaza, 8.5D RW GTs... I initially went with the overwhelming majority and tried a UK8 on the 4497, but it was just too short. While it's quite roomy in the toebox, the 4497 isn't a particularly long last. So I decided to go with the UK8.5 instead; it obviously has a lot of volume, but is an amazing fit with some Dr. Scholls gel insoles. I've also worn them without insoles, with the laces cinched up tight; my ankles are locked firmly in place and I get plenty of wiggle room up front, so it's not a bad fit that way either. Ymmv.
