Do you prefer the L or XL size? I have mostly L trees, but the AE recraft sent my MacNeils back with XL trees. They're tight enough to make it difficult to remove, so it makes me a little nervous to use them. But AE recrafting must know something, right?
I have a mix of L trees (all AE) and XL trees (all JAB). I love how the XL trees fit, besides the depression they've left on the heels.. They're much fuller and generally better fitting. I may sand down the rear/heel of these trees and then they'll be perfect. That said, when I fly, I take the lighter, large-sized trees (and a cheap plastic tree, rotating daily)
Also, FWIW, I only use XL trees in my loafers, but don't insert the heel as not to stretch them length-wise. Ideally, for these, I'd acquire an XL-sized tree with a spring.
Also, do people here use trees in their unlined chukkas? It seems a little counterintuitive to me, but I will comply if there is tangible benefit.
At the AE stores, they use rubber trees. I believe the heel might be cedar, but I don't recall? Either way, they don't sell these trees and I don't know where they get them. They're nicer than most plastic/rubber ones I've seen. I haven't yet used trees in mine, but if I did, I wouldn't use the XL ones ;-)
Btw, I'm literally on the way to my cobbler now to drop of my first unlined pair to repair the rip that made them seconds...
