Thanks for the reminder about the shoe tree. I got woodlore or some such. They are solid, shaped to the shoe and most importantly fit the shoe. Are my $200 Allen Edmond's worth purchasing Saphir Renovateur. If so, I'll pick them up. I would also like budget options for an older pair of AE's that I'm keen on keeping much longer. I think any shoes you want to keep nice are worth purchasing Renovateur for.
