Unknown to me until today, on the left shoe where the uppers and sole meet next to my big toe joint is a protrusion about the size of a pea. I thought I had worn them in, but a few weeks ago I did some serious day trips and ended up with a blister on the side/ball of my foot easily three inches across. I'm ex military, and it is the worst blister I have ever seen. A month later it is still healing. My feet were really sore at the time, but until I felt around inside of it just now I had just put it down to the distance I was putting in on those days. Infected feet are bad. Very bad. These are going in the garbage.
