Wow Bill. Do you use shoe trees? I work in a 600K sqft factory. J&M leather soles are my shoe of choice when have to stand a lot or give factory tours to customers. Now, I have a pair of rubber soled J&M and they kill my knees. My most comfortable but dont look as nice, are ECCOs.
P.S., I have had 4 knee surgeries and a big guy 6' 250lbs so I am very picky about shoes.
I do use shoe trees. It's the standing and walking all day that make my feet ache like crazy. I do have flat feet though so that is probably a contributing factor. Thicker, softer soles definitely cured the comfort issue for me though.
