These are great and true to size.  I wear a size 10 and have always purchased size 9 Chucks.  After reading reviews, i purchase size 10 Chuck II's and they fit perfectly.  And they are so damn comfortable!  So much more comfy than normal chucks.  I also enjoy the tech put in place to ensure that the tongue stays in place and doesn't slip to the side of your foot. 5/5; would reccomend.

**Update** just a little over 4 months after purchase, the sole is separateing from the shoe at the toe. Wtf. While these are more comfy than the original chicks, it seems that they aren't made nearly as well. Downgraded to 2 stars _
