Well they said their calf leather comes finished and they burnish it to get the shine. When I asked if it's CG she said it's not grain leather. Wikipedia listed the four types of leather for me and three say grain so I narrowed it down to the fourth option. The website says 'burgundy cobbler' on the shoe page. I don't know if that's just something to do with the color, like how cordovan is sometimes used as such.
the shoes you have are made off CG (high shine vinyl coat) i wouldnt recommend to try remove the finish!!
