A certain running chain let, lets call them Perspirationstore, confidently told me that I am a servere 'overpronator' and need the stability offered by Asics Gel Kayono viii (105.00).
They seemed to know what they were talking about so I purchased a pair. Now some 150-200 miles later I am visiting a physio privately for knee problems. I cannot say that the new shoes are the problem but it's cetainly possible. The physio who spent nearly an hour examining me told me that I am much more suited to a neutral shoes and should not buy a shoe for over pronation next time.
Clearly, I would have been far better off going to a high street non-specialist sports shop where no such advice would have been given.
I wonder how many other runners have been sold inappropriate shoes from these 'specialists'.
