They do it so that they weigh less
, so that they cost EG less to ship.Duh.
For all you (clearly) scientifically minded people who think that cedar/wood trees can 'absorb' significant amounts of moisture day in, day out. Think about it - where does the water go? Or does all the water that gets absorbed in the 16 hours they are in the shoe make somehow get out of the shoe tree in the 8 hours they are left lying around?
