After reading a few posts on here regarding having a Gait Analysis done, and running in the right shoe.
I highly recommend a Gait Analysis (try a few shops just to be sure) and also this website for independent review of shoes solereview.com/ .
They review all the different brands and also different types e.g. Neutral or Motion control.
I hope this helps anyone thinking of having a GT done and buying some new shoes.
