Got it. Technically that is just over a US size 9. For the purpose of finding the correct width, only the 27.31 measurement matters (not the associated boot size). The Arcade 158 Wide is 271. cm at the center inserts (waist measurements are not valuable for this purpose). That will leave you essentially no adjustment other than zero degrees for stance angles. If for instance you ride a very common 15/15 or similar you will be well within the confines of the decks edges and I would stronly discourage that.
Thank you for your advice seems I have a lot to learn about this width business. Thats so odd im like a 10.5 to 11 in snowboard boots and a 10.5 in sneakers who would have thought my feet were a size 9. Thank you for your time guess I have to find a comprable all mountain board.
