Rubber coating leather boots with lining

[Larryvaan]

If I am making a boots where is leather between rubber coating and separate lining leather, is there a problem when you can not oil or grease that middle leather ever? 

Does it suffer and lose properties such as pliables over time. There would be glue also both sides on that because I suppose lining is good to glue with sewing.

And I mean boots like Sorel Karibou

Does anyone having ideas or comments on this? 

Maybe this is not a big problem. If you use leather shank, or build multiple layers sole  from leather, those are also left without possibility to oil/grease.

Using chrome tanned leather might help a little to withstand not being able to take treat the leather. 

It will get moisture and sweat even there is glue against lining leather. But not that much I suppose.
