I hadn't mentioned my RUN & BECOME experience because this is flagged as an online store thread, but since they've been recommended by Ms Muddy T. I thought I should share my experience (POOR). While their fitting service seems good to me, their aftersales service stinks.
I bought a pair of Mizuno Trail shoes, which I returned less than 24 hours later as when I wore them at home on carpet for an hour they nipped in badly on my little toe. They had none in the size above and their range of trail shoes is quite small so I asked for a refund and they flat refused. I explained that I and my partner have both bought many pairs of trainers there and until this day not returned anything but the manageress was not interested in listening. Once she'd said her piece (their policy is NO refunds.) she walked away while I was still mid sentence and simply refused to speak to me again on the matter.
The sales assisstant that I orignally spoke to was quite embarrassed and sympathised. So she told me that the area manager was visiting that afternoon and to come back then, between 2.30 and 3.30. This I did, to be told when I arrived that the manageress and are manager were upstairs in a meeting and neither would see me!
Again the sales assisstant was embarrassed and apologetic but that was that. They simply refused to give me my money back, despite mine and my partner's years of patronage and this being the first time I had asked them for anything.
Now, I know they are not legally obliged to give refunds on non-faulty goods but some flexibility and descretion might be expected for loyal customers, particularly on trail shoes of which they have a relatively small selection and for which most retailers recommend walking about at home in to try them out (this my partner was told to do by an outdoor shop).
I will not shop at RUN & BECOME again.
