Was looking for something to put in my boots to keep their shape nice.  Especially the newer more expensive boots......found these.  Perfect.  I use them for my riding boots but unfortunately didn't order enough !  Ordered 2 and now I need more !  The only bad part is you end up paying so much for shipping.........my advice is to order quite a few................FYI- there is absolutely NO packaging with these boot trees.....I was caught off guard to just find these things floating around the amazon box but hey,  I LOVE that they didn't waste resources on dumb packaging !  WAY TO GO !  Buying 3  more for my UGGs and an extra for future boots......also- these ARE made of styrofoam  (but who cares? I was using rolled up magazines before)
