I did 2 days of walking last weekend in hard soled mountain boots (which I have not worn for a while) and on the way down the mountain I had an extremely painful stabbing session in both feet. It eased when I took off the boots and rested my feet the next day so I assumed that it was just my feet getting used to the inflexible boots and the day walking on stone.
I went for a cross country/ trail run the following day and had no problem at all but when I went running on a treadmill 2 days later after about 3k the pain started and became so unbearable I had to stop. I was wearing brand new trainers.
A few years back my podiatrist said I had less cushioning on the balls of my feet then is ideal due to cushioning being pushed towards toes so advised I wore cushioned trainers. I therefore always wear Asics Kayanos as these are supposed to be one of the best for this.
Could it be the new trainers? I thought new trainers were better before they wear down? Or could it be a more severe problem. I am due to walk 27 miles this weekend and dont want it to flare up again.
