Sator states (in his excellent thread): "The overall quality of their boots can be best described as basic high end comparable to AE and superior to Loakes." Only one opinion, mind, but if true, then RMW is nowhere near C&J 'benchgrade' in quality. Actually, I think he underrates them somewhat: they are far better than AE. Different league to Loake. Better than Barker, but below C&J and Grenson "Rose". That's my impression from having handled most of these boots.
RMW is a bit of an odd fish: one foot in practical, knockabout territory, the other in smart dress boot territory. C&J is dress boot all the way. Does anyone here wear their C&J for riding? It would be interesting to know how they have held up. As a knockabout boot, RMW edges it (leather not so important), but as a true dress boot C&J has it. But those RMW lines are so seductive! As always, try 'em on, choose, then regret purchase later! Odds not bad: 50/50.
