We always cite shoe trees as the most underestimated part of a man's wardrobe. Putting them in your shoes when not in wear is like giving them a good night's sleep — it just makes them feel better, and look better, and last longer. Ours are made from unlacquered cedar, which draws out moisture and odor. And when the cedar smell starts to fade, hit them with a little fine-grit sandpaper to bring it back to life. Try a pair.
