I have a few questions (I'll try to keep them short) which I'd very much like to get some feedback on. I've been a runner all my life (I'm in my mid 40's) and I'm an Ironman Triathlete, so I've certainly logged a good number of running miles through out the years. I had never had any hint of plantar fasciitis in all my years of running and competing, until I switched from a traditional 12mm heel to toe drop shoe, and began alternating between an 8mm drop shoe and a 4mm drop shoe. The 4mm drop shoe didn't feel right from the get go and I should have listened to my feet, but I just thought my feet needed time to get use to the lower drop. Needless to say, soon after switching to the 4mm drop shoes (the 8mm drop shoes felt good)I developed a solid case of PF. Is it logical to assume that lower drop shoes(4mm to 0mm)are a likely cause for developing PF, as lower drop shoes place more stress on the plantar fascia? I talked to one runner, who works in a speciality running store, who dealt with his own issues of PF for 2 1/2 years, before returning to running. He recommended I switch to a specific shoe that is extremely well cushioned (which I'm all for) but it's a 4mm heel to toe drop shoe (which I'm very leery of, obviously). When I return to running, would staying away from low drop shoes and returning to a 12 mm drop shoe, be my best bet for keeping PF at bay? And finally, when do I know it's OK to return to running? I haven't ran in 3 months, during which time, I've been stretching and rolling. At this point, I have no pain, and only very slight tightness, but not pain, in my heel when getting out of bed in the mornings. Should I wait until there is no discomfort, or sensation, at all in my heel before I return to running, or with new shoes and wearing a Feetures plantar fasciits sleeve sock (any thoughts on these sleeve socks?), can I return to short runs without re-aggravating the plantar fascia? OK, maybe not as short as I was hoping, but thanks for any input anyone can provide me.
