Are there any go to brands for good quality, non-adjustable shoe trees at a reasonable price? I recently purchased a pair of loafers from Gucci, who don't seem to sell trees. Given that they are loafers I think an adjustable length tree (I.E. the ones that supposedly cover a few sizes) would put too much pressure on the heel and mess with the fit. Crockett & Jones' trees are very nice, but they seem to be quite pricy these days. Ideally I need a brand that is readily available in the US. Thanks!
