Just finished 45 mile hike in Yosemite High Country. For the first time, no blisters. Have found the following to be very useful:
1. wear only one pair of socks (in spite of classical recommendations to wear one thin cotton pair under wool socks), "merino wool" type. Found
the brand "Darned Tough" to be terrific, though expensive socks (lifetime guarantee).
2. used Kinesio tape extensively. stays on better than Moleskin and is thinner. Do google search for "kinesio tape" or "Kinesio Tex". Has some history as general musculoskeletal tape for various ailments.
3. toenail trauma is reduced by taping aching toes (perhaps distributes pressure to other parts of toe)
Happy Hiking!
