Of boots and feet

I calculated that if I replaced my Raichle Montanga's with the La Sportiva Trango S EVO, on a two mile hike I would save my body from having to lift 5,922.56 lbs of boot. The calculation is rough but goes like this....

Old Boots weigh 6 lbs
New Boots weight 3.2 lbs

Two Miles of Trail run 10,576 ft

Average stride 2.5ft

Strides in Two Miles: 10,576 / 2.5 = 4,230.4

Weight per stride (old boot) = 3lbs
Weight per stride (new boot) = 1.6lbs

Total boot wieght for two miles (old boot) = 12,691.2 lbs
Total boot weight for two miles (new boot) = 6,768.64 lbs

That is an amazing amount of lifting your legs do aside from the act of lifting the rest of your body and backpack. Just my old boots make my body lift 6.35 tons on a short little two mile jaunt.
