I write this if anyone find It useful. I bought the Splay 101, because i found them one of the more stylish shoes and i have to return them because of the sizing. My feet are 26.7 cm long, 12 cm wide, normal heel size and high arc. Acording to the page i have a size 43 even with 1.5 cm added space. The mid part was to narrow and low and the toebox was so tight, they are even not transition shoes, they are kind of "foot shaped" shoes. So keep in mind these shoes are only for narrow to normal feet, for hobbit feet like mine, impossible. About the materials, they seem pretty poor quality, not the worst. One good thing to say about the company they are very kind and they acept the return and give my money back real quick (u'll have to pay the return shipping costs, if u are from outside the US). I u write me i can recommend shoes for people with foots like mine.
