We've just had a Sweatshop open here so went in to find new shoes. Was told they did a free gait analysis, which quickly became an insole fitting session. I told the guy I wasn't really interested and that I'd tried similar things before but never really liked them (they change the fit of shoes - make them too small), but he said there was no obligation, so went with it.
I don't know if they'd have refused to let me try shoes on without going through the process, but they never mentioned cost - in the end I asked and it was £45.
When they were done, they put them in the first pair of shoes, I told them I didn't like them and he put them to one side and we got on with finding a new pair of shoes. Overall just proved to be a waste of time.
I have to say I wasn't overly impressed with the level of knowledge of the person serving me - made some very strange observations on shoes and technology. I would expect more from Sweatshop.
That said, I have 30 days to try my new shoes and change them if they're no good. That seems a pretty good deal to me.
Could well be the problem - I noticed quite a few aches and strains when moving from a 12mm to 6mm drop. Having said that, now I've adjusted I far prefer the lower drop - seems to promote a much smoother, lower impact and more efficient running style.
As far as I'm aware, Saucony are pretty much on their own with their reduction In drop across their range. I think New Balance may have done it on some shoes too, but other than that I think most manufacturers still have a normal drop on their running shoes.
