You are not supposed to wear mouldeds at Feltham School, they don't like it, but I think Jamie is going a bit over the top. It does take a moulded boot, as we train on it every week and plenty of our players wear them. Personally I don't but that's a matter of preference. If you wear normal trainers you'll be on your arse, astro trainers or mouldeds will be your best bet.
Marler, they changed the astro at Feltham about 3 years ago. It's not as bad as it used to be, not 3G but it is good enough.
