The dishonesty (at least a bit, I think) is allowing you to order stuff that they don't have, while not making it clear when you order that the shoes have yet to be made. Sometimes you get lucky and they just happen to have what you want in stock, but you never know. They hold very little stock, have a relatively low margin business, and a complicated production and supply chain. Their shoes are basically ordered over the internet, often in English, Google-translated into Spanish, then ordered from their suppliers in China, who presumably also have the odd misunderstanding, half-made there by low-paid country folk in a sweat shop, then sent to Mallorca to be finished. If all that happens, they're eventually sent to you. With all this in mind, there will be (and are) delays as standard, and errors with some frequency..
But, a pair of shoes that sells for about 130 Euros ex-VAT, is pretty good value - unless you have quality issues and have to send them back, but even then, if that's one pair out of several, the value proposition isn't bad. I'm just wary of going for any of their more expensive lines, although as these are allegedly made in Spain instead of China (insights welcome), perhaps the mishaps will be more rare.
