No, we fit them on Europeans in the UK and all the lasts are developed in Europe and shipped over to be copied. Asian feet are a completely different shape to European feet anyway, it would be a mistake to fit them over there. But alot of the leg patterns were based on patterns from the 60's and 70's. We have made them bigger over the years and some stores make them bigger still, but you can't please all of the people all of the time, make them too wide and thinner people will complain. You have to try different brands as they all have different fits, it's just not possible to cater for everyone, unfortunately. Clothes are easy to store because they will pack away flat, boots are not. There isn't a shoe shop with a stock room big enough to cater for all fittings and tastes.
Duo are expensive because they are made in Europe and either made to order or in small runs, almost like sample runs. They are a very keen price for what they are, from my POV I've been wondering how they manage to do it at that price, plus the logistics much be a headache. It's consumers who have got used to not paying the true cost to make a pair of shoes. The price has actually gone down in the past 20 years, but the cost of manufacture has gone up by a lot. I've just (regrettably) had to move a range of shoes to China, because we just couldn't afford to do it in Europe anymore. Would you pay £150 for a pair of flat sandals? Thought not! it also explains why Faith, Dolcis, Stylo, Barratts, Priceless, Ravel and Shellys have all gone bust, because no one is making any money, they are being squeezed by rising costs (currency and EU anti dumping duties are the biggest problem).
Anyway, I'm working on a range of shoes for women size 8 to 11 feet. We are deliberately not doing a very wide fitting because Emotion does it. We had to make that decision. Its not possible to cater for everyone because the tooling up would cost too much, we want to do wedges for instance, but at that size, we'd need a pair of wedge moulds for each shoe size - at a £1000 a pair of moulds - we changed our minds!
