So to prove/disprove my theory, I did some basic research on three shoes I have been running in. Before I looked up the numbers, my gut told me that my Salomon XT Wings (the ones I was wearing when I got hurt at Superior) had me sitting higher off the ground. I thought my Cascadias had me the closest to the ground.
So here are the numbers:
Salomon XT Wings - Heel 25mm, Forefoot 13mm, Delta: 12mm
Brooks Cascadia 4 - Heel 22mm, Forefoot 10mm, Delta: 12mm
Vasque Celerator - Heel 28 mm, Forefoot 16mm, Delta: 12mm
So the data doesn't exactly support the theory. My Cascadia's are lower to the ground but my XT Wings aren't as high up as I thought.
So what does this mean? Got me, if you want to read a bit more here is a post where the author spent more time looking into it - RunBlogger Shoe Height post
I still think my XT Wings were a contributor to the sprain as they are a more beefed up shoe, at least I think they are. It is my nature when an injury happens to blame the shoes, much easier than blaming myself.
Of the shoes above, the ones that I like the most are the Cascadia's, I like them for shorter runs. The Celerators fit a bit different and I need to wear a thicker sock. The XT wings, I don't like and I have concluded that Salomon's just don't fit me well. I wear a size 13 and my toes get crunched a bit, I think a 14 would be too long, I do love their laces.
So as I retire the shoes above, what will I be running in in 2011?
Montrail RockRidge - Heel 21 mm, Forefoot 11 mm, Delta: 10 mm
Montrail Sabino Trail - Heel 19 mm, Forefoot 9 mm, Delta: 10 mm
Columbia Ravenous - Heel 20 mm, Forefoot 10 mm, Delta: 10 mm
So it looks like all 3 will have me riding lower to the ground, so if my theory had any merit, my ankles will have a good year, that is after I get one of them back to good health.
I picked up all 3 pair from SierraTrading over the last 3 or 4 weeks for $121.36 (including shipping). I ordered the Ravenous and Sabino Trails first but the Sabino Trails had a defective loop so I sent them back and although there was an issue with the return, SierraTrading came through just fine. I wanted to exchange them and instead they gave me credit. Turned out though they then offered me free shipping and I ordered another pair but I was also able to pick up the RockRidges for ($35.67) and of course I couldn't resist as I think Montrails fit my feet really well. So now I just need the snow to melt and I am set to hit the trails.
