I had a pair of Privos,Mary Jane style, last summer , and really liked them, but my size was 1/2 too small. So when I ordered this pair of Isograd, I got 1/2 size UP. They were much too long, so I am returning them for 1/2 shorter. I'd recommend ordering 1/2 size DOWN from what you usually wear. I sure hope they fit, as I love the feel. I'm glad the return shipping is free.
