Disagree: Not all unlasted trees are made equally. I have $100/pair C&J trees that beautifully fill my shoes from heel to toe, with full instep support and all, while I've found that the basic cedar trees that so often get recommended have too low of an instep, and aren't sufficiently wide around the ball of the foot.
Question of my own: This is surely in the shoe care thread somewhere, but I'd like an answer before trawling through hundreds of posts over there. How do you guys go about attaining a mirror shine on your calfskin shoes? I've just had my first experience with Saphir wax, and got a nice shine going on two pairs of my boots, but am having diminishing improvements with each extra coat of wax.
