I have my last set of Keens a fairly bad review but being th skins of guy who has to know why something isn’t working I started messing with the boots. Turns out it isn’t the boot but the narrow little insole they put in. I pulled it out and all of my foot pain went away. The set in there were pushing the outsides of my soles up and it was really a problem. Now no issues so if your keens give you some problems it may very well be the insoles.
