After a long debate with myself I finally took the plunge and went to sweatshop fir a running analysis. What finally swayed me was all the positive comments from a post I put on here. Now i'm not in the first flush of youth (menopause is closer than teenage years!) & not what you would call a toned up runner. Despite this the woman in the shop was great. I ended up getting a pair of trainers in last year's colour (who knew white was out of fashion?) & I got the insoles too. I've got a very high instep & I can use the insoles in other shoes. Been out running twice in the new trainers. I feel so much better - today my Nike+ app told me I had run my fastest mile!! So, if you're dithering about having a running analysis I say go for it!
