G-Man:
Tearing out the toe & heel cups is a field expedient method designed for when boot repair or replacement is not an option (like at Camp Mackall during SFAS).
You need to start SFAS with 2-3 pair of well broken in (but not damaged) boots. Otherwise you're starting the Indy 500 with plugs in your tires.
Get 2 new sets today. Wear one of them non-stop around the house/town (until it starts to rub or cause problems).
Continue your long rucks with the boots you've been rucking with until the new ones are broken in.
Personally, I like Belville's version of the Desrt Jungle. Mine broke in in no time.
Also, consider the boot insert you are using. If you have a standard (or cheap flat) insert, it doesn't cup your foot the same as a good one will. SOF Soles are good if you can find them. I also like the inserts used by Dean Kanazes for his ultra marathons (regular SOF Tec version). I've seen them at clothing sales for about $25, commercially for about $45-50.
