ZROMen's Lace Up Formal Modern Oxford Dress Shoes

Are these shoes made with genuine leather, or full grain leather?

you don't have size 9 it will fit as size 9.5?

How durable the outsole of the shoe? How long they would last before it starts to show wear?

My shoes size is uk 8 and europ 42, so the size in us is 9. but for this model there is no size us 9. thereforwhat size should i get us 8.5 or us 9.5?
