I thought it was a Dianese thing, the leathers over the boots thing, they say their gear is meant to be worn that way.
Might just be for the chubby legged
I always have me leathers inside my boots but I don't have dianese. Might give outside a try, athough it does make the leathers more suceptible to exhaust damage? it's cheaper to replace boots than a set of leathers.
Bit like bikers turning socks back over their boots in the 50 and 60's?
