The lower shell indicates they are size 29.5-30. The liners say 29.5 but maybe you have a moldable liner you would like to use. I do not think they are intec capable, but I'll only ask $50 shipped to you.
The colors are Very Dark Brown, Tan, and Gold. In fact, the other boots you mentioned like the Shadow and the Freecarve are not intec compatable either.
Hope this can help you! Let me know.
