Kardashian Kollection Over the Knee boot

bixio37 Are they black or gray? Listed as black but look gray in last picture :)

mariahprince01 @bixio37 they’re black.

bixio37 @mariahprince01 thank you. Also, what does the top look like? Is there a slit in the back? Elastic? And how high is the shaft? From the back of the foot heel to the top? Thank you so much!
