Do slow (2-3 seconds up 2-3 seconds down) weighted single leg calf raises every other day instead. No need to go below parallel on the eccentric (down) phase. 10kg kettlebell will do.
Can you describe the reasoning behind this? I have dealt with similar issues in the past and I'm curious.
All the PT resources online suggest eccentric exercises work best for achilles stuff, but my running logs from a few years ago suggested the calf raises worked just as well. Curious what evidence you may have for it.
Merely that going below parallel can aggravate the achilles further, no need to do it. Up and down do a level surface is just fine. The downward phase, without going off a step, is still an eccentric contraction I think?
Also don't need to go to the extreme ROM on the up portion to for the same reason.
This might help you:

There are vary few studies on achilles rehab exercises. Most of the advice you will find, as you have, is based on a single (or couple) of old studies. More recent studies have shown tendons adapt better with a higher load, no need for lots of reps.
Keith Baar would probably recommend taking 10-15g of hydrolyzed collagen and some vitamin c 45 minutes before exercising, which may bolster the adaptaion.
