I liked the design, primarily the reason why I bought. But I don't find it really comfortable to wear. Another is the size. I do not know how you meaure it but to give you an idea, my feet size is 28.5cm, I bought 28 based on your recommendation because you don't have my size. The thing is your 28 is still a little longer. Now if I try the next shorter size, how confident can I be that it would fit my feet perfectly?
