how many pairs do you have? I count 4 in the past week . . . you can always go to the Hoka Cliftons . . . soft as marshmallows. :)
there are two possibilities, cushioning the joint or diverting pressure from it. trying to determine which seems to be more effective. I have way too many shoes, but whatever it takes to keep running, eh? My feet seem to change sizes, and experience various maladies, I experiment a lot, and try to dial in specific shoes for specific purposes - the upshot is I could practically open my own shoe store!
i feel guilty, but I donate those that dont fit in at all or are worn to the level of being unwanted walking shoes. And as for the rest, I figure soon I'll have a critical mass of shoes, for various uses, fluctuating shoe size, injury... and I'll stop buying them - a lifetime supply.
