it's a bear.. have it since 2008, crippled early 2011 until 2013 with minimal running.
Stopped running for 6 months doing the eccentric work, the flat eccentric heel drops helped where the stair drops did not. Also did a lot of cycling, this provides a good flow of oxygenated blood to the tendon without putting any stress on it.
Hokas really helped my recovery. I did the eccentric drops both flat and stair 3 times a week as maintenance.
Recently got lazy and neglected the drops, the pain is back and bad, stopped running again and back in rehab for a month or two, we will see.
Back on the flat eccentric drops, also doing
Dave Roche's lunge routine since I suspect that weakness and instability of the supporting muscles and tendons may well be a factor. I'll add back calf strength exercises as pain permits.
