Skechers Cali Women'sVINYASA - GLORY DAY womens Flip-Flop

are these Sketchers counterfeit? or the real Sketchers?

What's the actual width? I have a narrow foot, would these be too sloopy?

Are these an actual true navy color as shown in the picture?

What do you do if you are a half size? Since these are reported to fit true to size, sizing up would seem too big, sizing down too small....
