Actually I’m nowhere near a place that sells Trickers, but from what I’ve read their lasts don’t really include combo types that accommodate a wide forefoot and narrow heel.What lasts have you tried?. I’m a uk9 and find the 4497 and 2298 lasts true to size, the 4444 last can go down a 1/2 size for a good fit.
I may be completely talking out of my ass on this point.
