I did Hoggs and Kretlins for a month trying to loot something big to sell to get my lowly Boar footies - since I couldn't get those to drop in the month before that. Remember, the boots were never about protecting our feet - it was a way to get us out there using more ammo and racking up more decay ($$ for
MA). They're not going to drop them regularly until the cash cow has dried up. Simple economics, not what we want.
