shoe trees aren't really meant for stretching your shoe out. they're to help leather shoes keep their shape and the cedar ones also absorb moisture which can do damage to the leather.

most have some type of spring mechanism so you can fit them into the shoe so not much use in stretching.

that thing that dirtyaccord posted a pic of would probably be better suited as it doesn't appear to have a spring.

otherwise a decent cobbler might be able to stretch your kicks out for you.
