I recently bought a pair of Reebok Crossfit trainers on sale for less than £35. Upon my researches, I am finding that trainers from the popular brands (e.g. New Balance, Nike, Reebok, Addidas) are not particularly difficult to find in this price range. Thinking back to my younger years, trainers in the same quality bracket would have cost a bit more (even in nominal terms), and that's at a time when you could get a bag of chips for less than 50p! Delving into the inflationary data, the numbers do indeed show that while prices have generally been rising year on year, clothing and footwear is one category that has fallen quite a bit. Go capitalism!
