Any advice on trainers/running shoes for the long of foot please. I'm an 8 in normal shoes but almost always find I need a 9 in a trainer/running shoe. However most ladies trainers stop at 8 and I have very narrow feet and find men's too wide hence my feet tend to slip around too much. I also under-pronate quite a bit. I have just embarked on the couch to 5k and I'm wearing an old pair of Nikes but they are slipping around on my feet. DH reckons I should try Asics - any suggestions pease?
