I think i probably have this 'mortons toe' that people are talking about, though it has never caused any pain and i dont have any callous under my second toes. It is actually quite difficult to feel my 'knuckles' but it seems pretty clear that my big toe knuckles take a step down, and my second toes are slightly longer than the big toes. (I also have ring fingers longer than my index fingers which I think I read may be connected.) Frustratingly, I have never had a problem with this until I started bare footing a month or so back to try and rehabilitate a slight bunion on my right foot. The bunion was due to wearing shoes I now realise were too small and narrow, not to the mortons toe as far as I know. However, have done a very very very small amount of barefoot and minimal shod running the last two weeks (never more than a minute at a time interspersed with walking, repeated 6-8 times) I am now experiencing a pain in the ball of my left foot especially when I walk on my kitchen vinyl floor barefoot. Particularly if I spin or twist on the ball of that foot. It feels different from the various stiffness discomforts that I was expecting from using my feet so differently. It is a sort of sudden pain - not awful but feeling like something that shouldn't happen. Note that this is not the bunion foot, which seems fine; it is the other one. I am feeling very frustrated by this and wondering if I am being silly to start running, but I have really enjoyed the little I have been doing.
