I just want to share relevant information with people who may be a little (or a lot) overweight. Please do go to your GP and ask for a referral to podiatry, about 5 years ago I was pretty much incapable of staying on my feet at work for more than an hour or so, I was diagnosed with ostheoarthritis in my big toes, I have ran all my life and absolutely love the feeling I get from running. It was pretty depressing being told to stop running, I started walking, and got some very good quality boots, the guy in the shop pointed out I was really flat footed, I had no idea I was. He suggested I go to a podiatrist.
I am really enjoying c25k, its a lovely introduction to running, as we get older and heavier our feet do some strange things, our feet are the most complex bone system in our bodys, look after your feet people x
