I went to sweatshop in Bristol just over a year ago and got the adidas footscan done and was sold the latest top of the range motion control shoe - Asics 2100. The bloke in the shop was vaguely helpful but didn't watch me run in them and as far as I could tell just went on what the computer said and what the latest model to sell would be. Looking back I was too reliant on the bloke and he was too eager to sell me the latest shoe. I got injured from the shoes and still have them in their sparkling glory with just about 30 miles on the clock - just haven't got round to selling them.
That said, the guy did give me 10% off - by asking if I was a member of a club and saying "don't need to see the card, just say yes".......?!??! Perhaps just a bad case of weekend staff???? I probably wouldn't venture that far again, with a perfectly good running shop in Cardiff... I just wanted to do the footscan thing really!!!!
