Foot care is probably the most overlooked important aspect of staying operational in hard times, non-permissive environments, and in SHTF scenarios. American's in general no longer walk around extensively in their normal daily lives, it's just a cultural thing. We drive, catch a bus, Uber, etc. almost everywhere we go.
