When I was there 5-6 years ago I wore leather Gtx boots, it was pretty sloppy mud.
The proper way for blister care is to not get a blister. Once a blister(s) appear, its too late. I fit and custom fit boots for 17 years in outdoor gun retail and I have commented many times, don't just buy boots shoes from an interweb recommendation, buy the footwear that fits you best even it if has a poor interweb response. You want no more than an index finger width of room between lonest toe and the boot. Try standing on the supplied foot bed to check the fit. I have had customers come in with boots fit way too large because they kept sizing up until they thought they fit, wrong answer. I have fit a true womens lasted boot (LaSportiva) onto men's foot. Heel blisters notch and post of the boot, Underfoot is too big. The first fix is to try different brand of socks. Nylon, foam and leather can be manipulated with heat and pressure but do not go out and by a heat gun, boot oven, boot bar and press, its an art to fit boots.
Use good socks, again not what is recommended. You have to abuse several brands of socks to find the one that works. Smartwool gives me hotspots, its just a fact. Bridgedale is my #1 sock of choice. In my experience 100% wool does not work, I prefer a 60/40 blend. Wool adds comfort and cushioning, the synth adds shape and quick drying. Socks change the entire profile of the foot and can take a good fitting boot to a poor fitting. With todays socks, no need for a liner and sock combo. Socks are not for warming, while they do, their primary purpose is cushion, comfort and control foot climate.
Start your day by liberally rubbing antiperspirant all over your feet and between your toes. I prefer Degree. What it does for your underarms it does for you feet, close off sweat pores. Good fitting socks. Good fitting boots. Use superfeet. I didn't buy into them at first either until I started using them. I have tried several and superfeet are what I recommend. Lace your boots up one at a time with full body weight on one boots at a time.
Long distance adventure racers tape up their feet with tape to guard against hot spots. I have done it but the days for long miles of trekking in tuff terrain for me are over. In my book, it you have to tape up your feet for a weekend comp, boots don't fit or at first try different brand of socks.
good luck
