I think you want at least 2" wide, but other than that regular all around touring skis are best for what I do. Comfortable boots are important. Boots and skis haven't improved all that much really, but bindings and pole handles and straps have gotten better. I like waxing my skis. Its fun. For touring its not that bad if you are too heavy for your skis. They still work, and in some ways they work better. Don't be afraid to try some cheap used skis. That will get you started. Just make sure the boots fit, and the bindings work, and maybe get yourself a good set of poles.
