Fits snug in the ball and just a hair on the short side. I removed the entire sock and put in a lighter thickness foam and fit was perfect. I think that the width of the insole is narrow for a comfort shoe brand. Not sure why they used a hard insole tuck board...would have been super flexible and softer with just proper thickness insole paper instead...i am replacing the whole insole so these will feel how a moc should feel. Love the silver leather though it is  bit too shiny? Hopeing to wear the leather out so it looks less foiled.
