I am a true to size W8. I purchased these in a M6.5. They feel just a wee bit big, but I think
the M6 might be too short. They are roomy, with a nice wide toe box. They feel like a well constructed shoe, even though they are canvas. I would have preferred a true white, as opposed to the beigey/creamy white, but I live the lugged sole.I think these will turn out to have been a hood purchase.
