Only kidding, I wear insoles myself when playing sport and there are some good and some bad ones. I suffer with sore knees and achilles tendons so go for maximum shock absorbing, and they do make a difference if you get the right ones and in some cases they cost as much as your shoes!
I went into the doctors the other week and said that the curry I'd had on Saturday really burnt my mouth and caused me some indigestion. He wrote furiously for 10 seconds and suggested the Curry Mahal on Portland Road, which was as it happens a good recommendation. I'm going back to the doctors...
