    It's a comfortable shoe that works well for a more casual kind of shoe.

    Great shoes, sizing a challenge

    I'm very happy with the shoes, but I had to size up pretty far to find a pair that fit. I typically wear 9 1/2. I ordered 10s previously, but it was too much of a fight to get them on because the heel of the shoe is angled forward. Fortunately, when I went to reorder, 10 1/2s weren't available. I ended up ordering 11s, which fit perfectly, but needing to size up 1 1/2 sizes was unexpected. Nevertheless, I will continue to purchase Reefs because I really like the shoes.
