Have made the transition to mid foot over the last 12 months and I love the way my feet now feel stronger. I was suffering with tendonitis and plantar fasciitus (apologies for spelling), but now distant memories. Occasional shin pain and tight calves means I'm constantly trying to improve technique. Low profile running shoes (Kinvaras in my case) certainly help. I just can't run anymore in heavy high heelers which feel like lead weights. So take the plunge and work on it.
