You wrote the snuff suede Indy from Alden NY is on red brick and then write "all three are on cork." As youbjust wrote, the snuff suede Indy at Alden Madison is not on the cork sole that Alden uses for its standard Indy models. As you wrote, the NYC model is on red brick, which is a comoletely different material. The Alden shop in San Fran offers the snuff suede Indy boot on the cork sole. But then again the OP asked about chocolate auede, not snuff suede, Indys.
