I usually wear an 8.5 or a 9 and the 8.5 is quite roomy and comfy. I was concerned about going spikeless, but the traction seems very good. Walked nine holes the first time I wore them and they were very comfortable with no break-in required. The only weird thing...every time I put them on I have the sensation that the footbed is cut wrong. It feels like the arch support is on the outside of my foot!! Maybe it's just because I got so used to the great arch support on my Eccos?? Nonetheless, after wearing for a few minutes that feeling goes away and I get used to it!!
