A comfy shoe makes a big difference, but I agree, standing vs. walking/running is a little different.  For standing IMO, you need a shoe that has support but basically remains comfortable.  Super cushiony might not be the best choice for this.  Wide toe box, so your foot can splay out a bit.
For me, walking/running/hiking, it needs to be LIGHT and relatively cushiony.  Lightness makes a bigger difference than you might think.  I have hiking shoes that are comfortable all day, but they are heavy and you notice it after hours of going.  The Columbias I just bought for the last run are 9 Oz.  
My other Merrells are 7.5 Oz, with no cushion, wide toe box.  Those are my "daily drivers", because they give good foot feel on gas and clutch and have a rounded heel.  They are minimalist, so not a ton of support, but not barefoot.  They are a hiking shoe, but they probably didn't realize it also works for driving.
