Personally I’m not into Grenson at all. I find a lot of the designs a little ugly (subjective of course) and I don’t like how their operation has been bought out and streamlined by a shrewd London marketing guy to cater directly for a temporary demographic (the heritage hipsters of the Brown Brogue Brigade). I think they're riding a trend rather that doing something original or authentic. Maybe I’m old fashioned, awkward or just a snob, but I like those companies who do the same thing year in year out, who wouldn’t dream of manufacturing abroad. I quite enjoy the tired décor, unhelpful staff and distinctly unfashionable vibe of the Tricker’s shop for example!
This recent article on Permanent Style explains clearly how Grenson is structure.
