So, I went back and ran the numbers for all the shoes for which I've tracked miles over the last 3+ years. Interesting. In that time I've run in and retired 6 pair of running shoes. I currently have 2 active pair. My average cost per mile was $0.134 per mile. Some other stats that caught my attention:
Most expensive: Brooks Adrenaline GTS7 (2007)During 2009, I used 4 pair of running shoes. One pair, Brooks Adrenaline ASR, was a pair that I bought at the end of 2005 for cold, wet runs. When Richmond, VA had 9+ inches of snow in March 2009, I dug out these shoes for 2 or 3 runs to keep my feet as warm and dry as possible. I would not have wanted to run on dry pavement or for very far with those shoes as they were worn out -- but, they kept me drier than other shoes would have done.$99.75, 454 miles - $0.22/miLeast expensive: Etonic Jepara SC 1 (2008)$72.00, 714.4 miles - $0.10/miLongest lasting: Etonic Jepara SC 2 (2008)$93.00, 817.7 miles - $0.11/mi
I wore out a pair of Etonic Jepara SC 2's that I had started wearing at the end of Oct 2008. I used those until June 2009 and had 817.7 miles on them. Then I started using a pair of Etonic Jepara SC 1's. When the rainy season started in Kenya in October, the SC 1's became my mud-run shoes and I added in a pair of Etonic Jepara SC 2's for drier runs. The SC 1's now have 504.6 miles and the SC 2's have a measly 62 miles.
Enough stats for now.
Run well, y'all,
