I wear a size 9 casual shoe/size 9.5 running sneaker. I always buy my Skechers golf shoes in 9.5 and this time it held true again. These in fact felt a little snug all over, but they loosened up to perfect after the first wearing. I didn't wear them in rain, but they held up well when I played 18 in very wet grass - socks stayed dried. I like the supportive fit and comfort. Would definitely buy these again!
