I stopped giving a **** about 'trainees' when I was about 24. Anyone who wears 'fashionable' trainees over the age of 30 is a major blimp if you ask me. Obviously inbred brands such as Ascot, Hi-tec, Niks and Kingfisher remain out of the question, but so is going for some expensive Addidas, Nike or Reebok that Year 7's have on their Christmas list.
Nah, once you hit your late 20's you need a mellow, nondescript, mid-range, comfortable pair of trainers from the likes of Lonsdale. Good brands are still OK, as long as they are nondescript, inexpensive and not being worn by Year 7's.
