I've never owned Paul Smith shoes and after a lil google search I found out their typically made from Buffalino leather which is obviously more rare and also twice as strong as calf leather, so I stand corrected! I think due to the Paul Smith items I've owned in the past not living up to their price tag... I've become a little unimpressed with the brand, plus I see accessories such as key rings and novelty wallets for £100+. It just feels like their cashing in on their success a little.
I still love your Paul Smith brogues you bought recently and will consider the brand for my next shoe purchase.
