If you don't like looking at toes, look away now!
If you have any form of toe or foot pain, here is a good link to work out what might be happening.Wearing normal everyday shoes/boots, I can walk around the street for quite a while and not get sore toes. Most days but not all days.
However, even though I have properly measured walking boots, after a couple of miles, the pads on my outer toes start to go under their counterparts, causing first soreness, then extreme pain.
To counter this, I have to plaster the outer toes:
Also underneath my right foot, just to the right of the pad of the big toe, I have a Morton's Neuroma (a similar thing is Capsulitis). It used to be very painful, felt like I had a grain of rice trapped underneath my skin. I now put a plaster here and if I remember to do so, hardly have pain whilst out on a long walk.
These problems seem for me, to be advancing with my age. I love walking in the countryside so if I end up eventually having to plaster my feet more, so be it!
