Just pulled the trigger one a black pair of 905 Carmina chukkas from American Tailors.
Given that they generally have very narrow last, I was surprised at how perfect the Simpson last fit me. I have a pair in the Forest last in cordovan and they are very tight!
Also, has there been any new shops that sell good shoe trees? I went into Double Monk who sell generic ones for $49, but are out of stock.
No ideas on shoe trees (I don't like the Loake ones from McCloud)? I would consider online and buy about 4 or so.
