Ten out of ten for Megan at the Sweatshop on the 5th floor in Harrod's. Londoners, I suggest you go there if you need a GA. She must have spent at least 20 minutes with me, highly trained, excellent suggestions and absolutely no pressure.
But, here comes the good bit... I was unable to walk, let alone run on the treadmill Nonone told me that it isn't easy. What a nitwit I felt as I was unable to keep time with the movement beneath me, what a cretin I am! What did she think of me? But who cares!
Anyhow, she analysed my gait anyway but without the computer and, thankfully, despite a gammy knee I do not overpronate. Tried on loads of shoes and went for a New Balance in the end in exactly my width for a pretty modest 70 Euro -- they were discounted.
Very knowledgable on socks too...do check her out. Thanks Megan and wos, am I impressed by you tread-millers!
