I waded through that site but a lot of what they do it a little high end (not that I mind high end). What I buy from Sportsdirect is £18 trainers (Slazenger or Lonsdale) that I burn through at work. I have to wear safety boots when building control visits, I know, but those throw-away cheap arse trainers and so confortable.
Ain't much else at Sportsdirect to talk about.
