If you have room in your closet to hang from the cuffs, the tension of the weight of the top of your trousers will keep them wrinkle-free and help maintain that crease. If I didn't have a half-height closet, I'd use these for all my trousers.
I had to resist buying those and the crepe sole shortwings VERY MUCH. I just bought a pair of Martegani chukkas for $90 on eBay and I just thought two pairs was too much. Still having to convince myself about the crepe soles, though.
