i wasn't happy with the durability of the leather soles on my allen edmonds. i only got a little over a year of wear out of them, but i am admittedly hard on my dress shoes.
i sent them to b.nelson instead based on recommendations on styleforum.com and askandyaboutclothes.com. i should get them back any day now and will report back
b.nelson gets my aldens when they need some TLC...
