The blisters and hot spots just need to be managed...all the time, not just when you're rucking. The guys that I saw with those issues 1) didn't condition their feet for what we were doing 2) didn’t try aftermarket gear ie, insoles, socks etc 3) when we got done, they’d lay around complaining about their pains instead of stretching and icing it down (preventative maintenance goes a long way) 4) when we got done, they took a shower and ran off on libo 5) when they did get blisters/hotspots they’d panic and try something outrageous that someone else tried and worked for them. Stick to what you know and what works for you. It’s simple, if you want your feet to feel good, take care of them. If something hurts, make a note and research it, you’ll find an answer and solution. Try Dr Scholl’s website, it’s full of great knowledge regarding foot pain. I worked out all my kinks and practiced good habits regarding foot care before getting to ASPOC and A&S, it became a habit so that was the last thing on my mind and never became an issue.
