I wasn't impressed with Up&Running in the triangle. In my case they ordered soem shoes that took ages to come and then they gave me the wrong ones (not wide fitting). If you're young, female and attractive then they will give you loads of attention. If not, then they've wandered off literally halfway through our fittings to serve new female customers.
There is however a brand new shop in town, opened last week in the Arndale opposite WH Smiths, with full gait analysis that is part of the Sweatshop chain - She runs, he runs. Was in there last week for the 20% off opening deals and found the staff helpful and pleasant, but didn't see the gait analysis as it's done in a nice little private area at the back of the shop. They also do a gurantee on the shoes beign right for you - if yoou don't like them then you can return them, check the website for the details of that.
I have used Sweatshop in Hyde and they are very very good, so I'd either go for them or the new one in town (assuming the same training).
And personally, I would suggest you do buy from where you get the anlaysis done otherwise all the places that do this will go bust and we'll all be running in the wrong shoes. Second pairs, that's a different story, but the first...
