I've been meaning to share some of my views since I did a little 60-miler over some of the rockiest parts of the AT recently, in good old Rocksylvania. I managed 60 miles in three full hiking days with not even so much as a hot spot, leaving my blister treatment pack untouched. This is in BIG contrast to how I fared on the Florida Trail, with no rocks or hills at all. And I don't want to give any false impressions, I'm very new to this and very humble about it. I've experienced the pain of said blisters, as well as miserably aching muscles and some pretty severe thirst.
First off, let me give some history. I live in Florida, and if you want to do some awesome Winter hiking, the FT is the place to do it. No rain, beautiful skies, and weather in the 60's and 70's. I got the idea in my head to walk through Ocala National Forest, and planned out 4½ days to get it done this past winter. I trained, shook out my gear, and eventually got dropped off to start the walk - with, of course, a pack that was a wee bit too heavy @ about 38#. I was wearing a pair of Asics trail runners (½ size too big) and some Darn Tough socks. By the end of the first day, I felt blisters forming on my heels and up under the balls of my feet, you know, the typical places. I lanced one that night, and the next morning I got up, shoved my feet in my shoes, and started walking. Being that it was 35 degrees out, I was looking to get walking very quickly. I wasn't wearing gaiters, and sand kept getting down the back of my shoes. Not good. The blisters, of course, just got exacerbated. I did some good mileage for the 2nd day, having had only about 9-10 hours of light. But by then, I was in trouble. My right foot swelled, and I had a blister starting up to the top of both feet, between my big and index toes. Walking on the 3rd day, I could not even appreciate all the beauty around me (and there is much in the Ocala National Forest)... all I could do was wince on each and every footfall. I had to call my girlfriend and have her come get me at a little community store in the middle of the woods. I did 50 of the 70 miles, but my feet looked like hamburger and I couldn't walk right for days. I know so many of you have been there. It's not fun!
This spring, I planned a little outing on the AT near where my parents lived. In fact, I got some good info from some kind souls right here on WB. I purchased a book called "Fixing Your Feet" and proceeded right to the Prevention section. I planned on using the same Asics trail runners because I knew that it wasn't necessarily the shoes... I wanted to prove this to myself. I was also super concerned about blisters putting me of the trail again. Over the course of a month, between intense trainings, I purchased: Spenco blister pads (for the heels and up under the balls of my feet), new insoles, Gaiters (from Montbell - AWESOME), Wigwam merino socks (three pairs) and that Sports Glide crap that stays slick forever. This stuff was my true saving grace, I think. I purchased treatment stuff too - lambswool, moleskin, toe caps, and the like... and never used any of it. I just did the standard drying my feet out at stops, slathering the Sports Glide on potential blister areas at least twice a day, and changed my socks twice a day. The gaiters kept all the grit out, and I literally felt my feet 'sliding' in potential hot-areas, rather than rubbing and starting blisters. From Port Clinton, I walked 16 miles the first half day, 17 and 20 the 2nd/3rd day, and 8 on the last half day where my father picked me up in Wind Gap. We know this is a ROCKY section, but yet I had not a blister to be seen. If you use gaiters, Spenco Pads, Sports Glide, all in conjunction with quality socks and halfway decent shoes, I think you put your blister chances down to the 20% chance range no matter what the terrain. I know wet environments may change this a bit. And, maybe someone will have a differing opinion. As a side note, I think my lighter pack weight (29# with H20 and consumables) helped too.
Sorry this has been such a wordy post, I just wanted to share some of my trials and discoveries with the hope that someone would NOT have to go through what I did. In short - a pound of prevention was worth a ton of cure! Hope this helps.
