I really don't mean to contradict you in the sense that I respect your observations and experience. That said, I put the shoe trees in right away and have never noticed an issue myself. I was conflicted on this until I read Vass's book. He says to go ahead and put the trees right in. In the end I think this stuff is very hard to quantify and the main point is that you should use shoe trees.
buda-I'm fine with your comments. I think everybody agrees that shoe trees are a must for your shoes to look their best over time, and to minimize creasing, or even curling. The second aspect...that of allowing the shoe to vent, or cool off is my opinion. To further clarify...it's difficult to know how much a persons foot sweats, and another factor is how often is the shoe worn?
Here's what I do know is fact for me. My foot does moderately sweat, and I live in Texas which gets very hot in the summer. When I was younger I could not afford a large collection of upper end shoes. Many of my shoes and boots got worn several days in a row. I noticed the inner leather liner would wear through, or crack where the foot flexes. Usually in the area of the shoe or boot has a cap (inside between the outer leather and inner leather)....at the edge where the arch tapers down. In some cases the leather liner would just fall apart. During this time frame I was using shoe trees. Back then I would put the shoe tree in immediately. However I was getting the inner leather liner failure as mentioned above. Back during that time frame there was a Church's shoe at the high end Galleria mall. I talked to them about these issues and what I could do to extend the life? I wanted to know before I purchased my first cordovan leather shoes. This guy was the one who told me to let my shoes vent a while before I put the shoe tree in. I tried it, and what I found is that my shoes dried out inside a lot faster. Everybody's foot is different, climate where worn are too. What I do know is I've not experienced a failure of the inner liner since I started venting for 30 min after wearing and using the 1 day worn and 2 days off method. No doubt it's extra work to allow a 30 min vent period but it does not hurt anything either. I'm getting into details because many of the members reading this only have a few pairs of nice shoes and I'm trying to give advice to newbies too. No doubt you are not new to this forum and I've got a lot from your posts.
