Somehow in over 40 years of hiking I have avoided serious injury from the activity. Last week I was diagnosed with Plantar Fasciitis in the right foot. The pain in my heel (radiating from the little toe side of my foot) did not follow classic symptoms typically felt in the arch, and is not the result of a stress fracture apparently. The MD gave me a series of exercises to do so the tendon(s) could strengthen, no night brace however.
This all has me thinking about how the condition can develop in people who walk hundreds of miles a year in various foot gear, I thought there may be a pool of knowledge that might provide some answers.
For the past 8 years or so I have worn Asolo 520s for any hiking done in all seasons. In the summer of 2014 I made the switch to trail shoes and found them very comfortable. In spring last year I got a pair of trail runners that were equally comfortable and lighter. Between these two pairs of shoes I have put on about 800 miles over the past year and a half. I use the 520s in winter (typically from December through late March). In July I noticed a minor problem in the outside edge of the forefoot that would come and go. Eventually the heel pain started and has gotten to the acute stage, which led to the above diagnosis over time.
In pondering this ailment, one thought I had was I may have pushed harder with the more flexible shoes (avg MPH went from about 2.8 - 3.2 in the 520s to 3.8 - 4.0 the shoes), though I would think with several thousands of miles over the past decade any tendon flexibility would have been maximized in the foot.
My question is this, does or can the flexibility of footgear cause or otherwise irritate this condition? Does the heavier boot with a higher heel provide a benefit for this condition, preventing its development over time? I never had any foot problems until this past July when this started. Does anyone have any thoughts on this?
I am also curious how long this condition will last (MD was nonspecific with this). I took myself off the trail and basically stayed off my feet since December 11th, but there was no apparent lessening of heel pain after 3.5 weeks of not doing much. My MD did not say to stop hiking, in fact she encouraged it due to its overall exercise value, which goes against some of what I have read about this. I am understandably interested in what worked for those with a similar Fasciitis complaint.
