Shoe tree is well shaped, wood quality is excellent, spring tension is just right for the size (my large size trees fit everything from 10-11.5), and fit and finish is great for the price. Bottom line? Spending an extra 20 bucks to keep your shoes looking and smelling good (and making them last longer) is a no brainer. Go for it, you'll be glad you did.

I think this is a well-known tip but I'll throw it out there anyway; sand your trees once in a while to expose new cedar to make sure it continues to work like new.
