I'd like to share my recent running shoe buying experience.
I treated myself to gait analysis and a new pair of running shoes a few weeks back at 'Sweatshop', scary, scary money, more than I've spent on footware in my life, but I reasoned it would be worth it as the 30 day guarantee alone was reassuring.
After my first run out in them I had the tiniest of aches start in my Achilles which didn't bother me too much, the shoes in themselves felt lovely and comfy, although the foot strike felt different as the shoes were 'guidance' and bulkier than the minimal Nike frees I'd been trotting about in since January. A few runs later and the ache grew after each run but would disappear after an hour or so, until last week after an easy pace 5k it spread to my calf and lasted days. I posted a question here and Ianodatruffe sensibly suggested it could be a transitioning issue and that I should go back to the shop for advice.
Off I went this morning not relishing the task off taking something back to a shop, it was very busy but by chance I ended up seeing the assistant who had originally analysed my gait and she was extremely helpful. She asked me what I wanted, would I be happy to persevere with the shoe as she suspected it was a transitional issue to do with altered foot strike that may resolve with use. So we decided that I will give it another couple of weeks of reduced mileage, run/walk and even though by then I will be out of the official 30 day period that will not be a problem. She even gave me the days she will be in so she can personally deal with it.
All in all, I'm very happy with the response and attitude. I'll be even happier if I can run again and hopefully get along to the Great North 10k next month, she did reassure me that the training miles are in the running bank - hoping she's right.
