go to a shop that has both boards, take your boots and put your boots on the board where you'd put your bindings and see how they fit. But size 10 and only 4mm difference...not going to matter much imho...ur going to be fine
...but idk I got size 7 feet and 25.0 is my limit for waist width....and prefer a 24-24.75....though my Charlie Slasher 164 is 26.0
The Jamie Lynn has a straighter side cut so it will be about the same width at the inserts
Received the board yesterday in the mail, it fits perfectly. In fact with my boots I have 1" over hang on either side. Shoes off I have about a 1cm over hang at 15/-15 deg at the inserts with heels at the edge. I love the graphics of this board! Can't wait to get out and try it. Unfortunately, I will be in Arizona until December. Hopefully Arizona sunrise will have some good snow this year!
