Skechers Women's Reggae-Sew Me-Boho Woven Strappy Slingback Sandal

How is the length? I usually wear an 8.5 but in some shoes I size up, others I size down.

Half sizes Size up?

Can the backstrap be tightened? I have a narrow ankles.

Is there a reason why this company can’t seem to give you the same colored sandals????
