Seems to me that Leffot are getting some harsh press here. I should point out at this stage that I've never bought either from them or from AFPOS, and my only AS shoes came from Yoox (who are assholes).
First of all, the apparent price difference looks worse than it is: if you're in the US, then you have to add shipping and possibly import duties to the price. Leffot have already paid the shipping and the duties. They also have to add 10% NY sales tax. Once those things are taken into account, the difference might be pretty small. Second, they might not get the same price wholesale from AS - nobody will ever know. AFPOS have no competing shoes at the same price point and might get a better rate. Leffot, by offering several brands in that range, might lose out on some wholesale discounts. That would not be unusual.
But third, and this is a biggie too, Leffot is a shop. With rent, heating and cleaning bills, property taxes, and someone who has to be there all the time to take an interest in your feet. The overheads are massive compared to an internet-only business that takes a PC in the living room, and flexible working hours. No disrespect is intended to AFPOS - they clearly offer a fine product and a very helpful service. I buy from other online retailers all the time, and service counts. But there is a clear, qualitative difference in the retail service if you can physically try on a range of shoes. All in all, then, accusing Leffot of charging unfair prices is probably a bit harsh.
Harsher still is to call them "predatory" for not allowing their customers to circumvent them and go direct to a wholesaler - or an agent from another market. When you take an agency (and I have some myself in another business), you normally have three specific points that it all comes down to: 1. How long - normally a fixed term with some option to renew at intervals if everyone's happy. 2. Where - a fixed geographical or customer base. It's unusual to take a distribution agreement that covers the whole world, even in a less formal wholesale arrangement. And 3. What - the specific products or services you will sell, that might not include the principal's entire range.
As a fellow small businessman, it sounds to me like Leffot and AS are getting a beating for not very much here. Somebody put his balls and probably his house on the line, and invested his money and his time in opening an expensive shop, employing people, signing up for a bunch of hideous bills and probably loans, and persuading a collection of find shoemakers to supply through him. He did it. For real, at his own risk, in order to make something beautiful and bring these products to the US for you to hold in your hands. Forgive the man for wanting to get paid, and not wanting someone else to take a free ride on his efforts and undercut him because they took a less customer-focused and therefore cheaper business model. Likewise, AS should be commended for not screwing over a man who has invested in physically bringing their products to a new market.
There is a serious point about where to buy outside the EU or US. Clearly, AS need to spell out where their authorised re-sellers are for any given market - their fancy website gives no details on this important point, which is odd. But I'm sure either AFPOS or Leffot would be happy to find out and tell SF-ers-of-Asia like myself, and will do so in due course. It sounds to me like they've worked this first issue out in a gentlemanly manner, and I'm sure either or both of them will be able to clarify this shortly.
