Thanks Hilly - that's really useful. I can't buy running shoes where I live (well, I can, but it's a choice of two or three - men's - models, so if I can't get back to the UK I either buy what I've had before by mail order or take a chance and order something completely different! I've had a lot of success with Saucony in the past and was thinking of trying the Praxis... I'm wearing NB 765's at the moment but I feel too far off the ground and they are a bit too bulky for me...I'm also wearing out some Mizuno Wave Mercury shoes, very light and they feel fast, but they don't like me over long distances, and have caused the death of several toenails!
