JoS. A. Bank has cedar shoe tree on sale every now and then for $7.50. I buy like 10 at a time, with free shipping, no sales tax. 45 for two is not a slick deal.
gamaThis is true, but those are a very different grade of shoe tree. They don't have the spring-adjustable toe section, the dual tube spring construction, the brass hardware, the more attractive shape, etc. And most importantly, JAB ones are identical for R and L shoes, whereas these are shaped differently for each shoe in a pair. It's a personal decision - neither is a bad option, but these are definitely better.
