Womens Nine West Leisa Ankle Strap Sandals, White/Gold Combo

I am generally wear a 9 but found that these sandals run large by 1/2 size. I may reorder in an 8 1/2 but I'm not sure that the ankle strap is right for me. It's hard to say as my foot was sliding forward. Nonetheless this is a very pretty sandal at a very reasonable price. My advice is to size down, especially if you sometimes wear a half size smaller in some brands (which happens to me more and more--size inflation in shoes too?)
