Rubber versus Felt Bottom Boots:? 

Rubber boots are generally better out of the water while felt can be fantastic in streams with a lot of moss and rocks that are covered in plant life.  Always check regulations: felt is not allowed in Yellowstone, Alaska, and New Zealand. Do be careful: in the winter felt has been known to freeze and make life on the bank a bit slippery! There are particular waterways, Putah Creek in particular, that many guides insist on felt to wade.  Cleats can take some getting used to but can be life saver in big and fast water like the Madison.  We recommend having cleats on hand as some guides in areas with fast water require them.
