Fishing Waders ?

[bigdog]

I plan to purchase some 'chest high' fishing waders, but have never bought this type of product before, and looking for suggestions.

I see some 'chest high' waders come with 'stocking feet' type and others
come with built-in boots, what are the pros-cons of each ?

Still confused, ad sorry for such a silly question, but If I purchase the 'stocking type' waders, do I still need to wear boots to wear ?

Thanks !
