but that's very cold for the feet!

From experience I can tell you that a granite staircase is not exactly warm on the feet. But since you are not standing on it for even a minute, that doesn't really matter. The advantages outweigh for me: granite is indestructible, looks good and is very quiet. In our old house you don't hear when someone is walking on the stairs.
In the new building we paid an extra 1,800 euros for the concrete staircase, but without covering. The granite covering costs just under 3,000 euros (treads and risers) plus installation.
