Swooosh - My Reg road tested them before they became issue kit. We all got two pairs each. One for runing, one for gym work. They were the dogs nads I tell you! All air cushioned and padded; I mean they were good.
Then, two years later when working at the ATR the word came down that they were about to be issued... I spent the entire evening telling the guys in the Mess all about how good these things were.
Next morning off I trot to claim my prize and what did I get?
Rather peculiarly, they manage to rip the skin from my toes between the end of the toe and the actual foot... It's really painful, but luckily they were only enforced in Phase 1! My last 'risk reduction run' broke my personal best, but I could barely walk afterwards! Not a good sign...
As a recruit we wore the black issued 'road slappers' then once in battalion we could wear our own trainers and as the Silver Shadows were the only real training shoe on the market the vast majority of us bought them, never did me any harm.
Silver Shadows - another excuse and another reason for people to whinge!!
Sorry forgot to say; unless you wear them and go sick until a body of evidence is built up. Nothing will ever happen the problem is no does everyone buys there own a cheap pair of trainers lasts 20 years instead of 2 pairs of decent trainers a year.
The AMS/APHC are now really good at identifying trends but unless there is a trend to identify
I have bought silver shadows in the past - admittedly the slightly better ones and found them to be pretty good. Fair enough you would not be mistaken for a drug dealer in them but so what if they look a bit crap.
