Lads .......... be very careful about you buy and where from, there are copies going around, the lad in a shop where I bought mine was telling me, and to be fair if you can get copies of everything else of any value then there's no reason why there wouldn't be counterfeit boots around especially as they are £150 a go.
There's fake everything, Timberlands, Trainers, sportswear, watches, Barbours, anything you want.
Personally I'd say that for the extra you're better off buying them from a proper retailer.
Buyer beware and all that.
