Just to pop back and say that since they've been back in touch, the customer service from Brooks has been phenomenal. I would say above and beyond what I could have reasonably expected.
To put the record straight (for those who may stumble across this thread in future), the way the seam is stitched, is deliberate. The aim being that for most people the tongue would sit flatter on your foot, creating a better fit. Like all these things, it doesn't work for everyone and it seems that my particular type of hobbit feet fall foul on this occasion. Having said that, Brooks have very kindly found me a solution and I would have no hesitation in buying a pair of shoes from them again.
I promise they didn't make me say this! It was rather nice to have such fantastic contact from a big company. Makes a very pleasant change.
I have contact lenses which I wear for a month at a time (so one pair a month), plus solutions, eye tests, reductions on glasses for £13 a month from Specsavers. It's not changed in the five years I've been having them, but £36 does seem expensive, although I did originally look at Vision Express and that was £45pcm for the same lenses.
Brooks weren't interested when I emailed, but I spoke to the chaps at Runner's Need and they said they'd pass on my comments to their rep. I do otherwise find the shoe comfortable, and they feel the best out of the shoes that I'm told would suit me, so it's annoying.
