Damn... really? I like the mahogany finish and it would have been great if they continued with the option for boot trees for MTOs. I can understand that streamlining the last of the shoe trees is meant to cut costs but why not keep the mahogany finish?
It's the wrong kind of buckle. On the link you provided, the metal in the middle slides to lock and prevent the side adjusters (fabric part) from coming loose. Without that function, the fabric will easily slide out.
