Back in 69 we did not have trainers as we know today. Only plimsolls and these were only used in the gym and not worn in public. We used to run in old army boots for boxing training that I am sure was for punishment more than anything else
The first time I saw real trainers was around 1980 when a bloke I was training with ran to the Dojo in Adidas ? ( the ones with the 3 stripes down each side) and at the time I did not consider wearing them out socially but bought a pair for training. When I did buy a pair they were the astronomical price of £23 that I thought was way over the top for a pair of plimsolls. But they were certainly a new foot comfort experience.
I am still not that keen on wearing trainers today but I seem to always have a pair of Reebok Classics that are ideal for walking on holiday but I do not generally wear with jeans for social wearing
The first cool trainers were the brown adidas samba that i think hit around 79 before then plimsoles inc Green flash were for 5 a sides only ... was the hip hop kids in NY then later the casuals in the uk that turned them into life style choices ... any man with any skinhead / Ivy intention should steer well clear of anything more casual shoe wise than bass wejuns IMO.
