And while at it and talking about ingredient lists. Do these protectors generally contain silicon, even if no ingredients are listed or not? I bought some moneysworth suede protector when getting some cheap suede beaters, so that's what I would use for now.
Answer 1 (from @benhour ) : Most of suede protectors can be used on any kind of leather without any problem (i have used it once without any problem just for experimenting purposes only) ! Tarrago and Collonil state it on the can (can be used on leather-suede ets)!!
Answer 2 (from @chogall ): It works, but why? Leeds is made from finished leather with a protective top coat AFAIK. If the shoes are made out of some unfinished leather/crust leather, it could help.
On the other hand, the effectiveness of water protector really depends on the severity of rain fall expected. They were absolutely useless in monsoons.
I would worry more about the rain if its leather sole; works in light rain, but water will sip into the insole if its heavy enough.
