I just needed a leather work shoe, not really the non-slip, but it doesn't hurt, right? I'm always a little leery of buying shoes online without trying them on, but the 8 1/2 fit true. I'm usually an 8 in heels or flats (no socks), and an 8 1/2 or 9 in sneakers. The 8 1/2 feels very good. I wish the shape of the toe was a little more oval (it's a little too square/flat for my taste, looking like it "chops off" my toes), but it's no big deal. They have a nice low profile from the side, of which I'm a fan.
