it's an old saying about brown shoes and working environments (particularly London because presumably people don't wear suits in mines or on farms)
Beyond brogues I am currently liking some blue suede desert boots but my favourite shoes are a lovely pair of slip on john lobb and a pair of black whole cut edward green shoes, both of which I've had for years. Unfortunately my budget for sartorial treats has plummeted somewhat since banging out the kids
I have some really nice blue suede shoes from River Island, yet to wear them!
