I took a pair of AE Cliftons I won on ebay to my local department store to get some Cedar shoe trees. Unfortunately they do not carry AE shoes let alone their shoe trees, so I have to live with the generic cedar brand which still smells ok. The lady who served me suggested a larger size where she really had to use elbow grease to get the thing into the shoe and on the right shoe she couldn't get the back part to slide into the back of the shoe and instead allowed it to hang out. Her point was that the main job of the shoe tree was to keep creases out from the front while whether it fitted the back was negligible and that I was better off with the larger size. The next size down fitted in properly however not as tight at the front as the larger version Maybe I did the wrong thing but I went with the proper fitting size. I was interested in knowing whether what she said was correct about the shoes tree serving no purpose other then keeping the creases and shape of the front part of the shoe. She seemed to be a mens shoe enthusiast and loved the AE's.
