I started out with Lone Peaks 2 . 5 medium cushion and switched over to the Olympus 2 . 0 very cushy by the time I got into the desert . I ' ve been using the Lone Peaks the past 3 yeas for trail racing so I started with the proper adaptation for zero drop . The cushion with them is pretty good new . And pretty good if you only wear them for 1020 hours a week . But when they are pounded on for 12 hrs a day , 7 days a week , the cushion wasn ' t enough for me . The stock insoles disintegrated . The cushion compressed . I felt every damn rock and was strategically tip toeingheeling because of it . There are times when the trail is nothing but sharp rocks and there are times when I was too tired to place my foot correctly . I switched to the Olympus starting in the Sierras and while they are high , I probably fell less overall because not every misstep on a rock or branch was painful . Coming out the the Sierra ' s , I average 28 mi per day from North Kennedy Meadows to Burney without any problems . My base weight was 10 . 5 lbs . I generally carried ' extra ' water , so an extra 2 lbs from there . Food was pretty standard at 34 k calories a day .
