I think my ergonomics are pretty good adjusting for age. Unfortunately I can't go back and remeasure material and construction quality from years gone by. My perception is that the shoe uppers are now all stiffer and less flexible than years gone by and the the sole materials are hard and have no give. I've gone to multiple shoe stores looking but have come up empty.
