I have been on a crusade to find the most comfortable dress-casual shoe.  Many shoes fit great with their uppers, but the bottoms are agonizingly uncomfortable.  Most competitors have aggressive soles (that seems to be a fad) which come through the bottom insoles feeling like pebbles.  Even quality shoes with hardly any aggressive sole still aren't kind to the balls of my feet.  I am not diabetic, but do suffer, as many older folks do, from "fat pad atrophy"--that is, the cushioning under the balls of the feet and heels has basically disappeared and, no amount of padded inserts make up for that.  Nevertheless, Keen is the most comfortable casual shoe I wear.  I do have very comfortable hiking boots from Keen and that's what gave me the idea to check out these walking "sneakers".  They are a little unusual looking (funky, strange?), but comfort comes first.  I'm not sure HOW Keen can get it right when it comes to under-foot and toe box comfort and most of the other manufacturers can't.
