Almost all makers produce "re-badged" shoes, often to a different standard from their main lines. Even Edward Green used to this, e.g. for Foster and New & Lingwood. However, except among the cognoscenti here, their reputations will be based on their own lines. Sargent are clearly capable of producing high quality shoes, I would say on a par with C&J's top offerings. The question is can they market them successfully themselves, or will they rely on resellers?
