I bought this to wear to my Zumba class. After reading the reviews (glad I did) I bought a full size larger. I am usually comfortable in a ladies 9 or 9.5. I bought a 10.5 and they are perfect. Not exactly how I thought they would be based on the pictures. Mine are completely black, no red trim as pictured, but that was fine with me. They fit perfectly and more importantly were super comfortable during my class. I would highly recommend, just make sure you get the sizing right. As another reviewer stated the seller really should add a disclaimer that they are sized smaller than usual.
