W2298 Last: 10.55US Men's Brannock: L 13A, R 12.5A
I have Tricker’s Stow in size 10 (4497s last) that are a bit snug, especially with thicker socks. Those were sized in store and I was a bit overwhelmed by the whole Jermyn Street pomp of it all and probably went half a size too small. This 10.5 in the W2298 last appears to fit me far better, so far at least!
