After struggling with niggling injuries for the last month which eventually resulted in me dropping back from week 7 to week 3, I decided that part of the issue was my brand spanking new Mizuno running shoes. Just outside the 28 day window, I took them back to Sweatshop to seek their advice.
I couldn't fault their customer service. After discussing the problems I was experiencing, they did the whole gait analysis from scratch, tried several other pairs of running shoes and happily exchanged them for a pair of adidas. Been running for over a week in them now and am feeling the benefits already.
Old fashioned customer service at its best!
