I had been waiting to buy these since I saw them and am so happy I finally popped on them. They are great looking and comfortable as heck. I have a wider flat foot, so I went half a size up. That works, and I wear a thinner sock. With the wool lining (love it!) I wear more slippery socks to avoid creep down. The arch support, someone else mentioned was too extreme. Like my other OluKai shoes, the support goes down with wear, conforming to your foot. Mine "broke in" in an hour or so of walking. The leather needs no breaking in, soft and rich. And the perfect warmth for my Michigan winters. Thanks!
