As the name implies, I always thought that panda shoes are all black and white, but I saw in JD.COM the other day that besides black/white, there are also gray, white/navy, but the latter two colors are out of stock. Look carefully, the silver you said is a bit like gray. I will send a picture. Do you think it's "silver" you said?
To tell the truth, this gray is really beautiful and looks particularly elegant.
