I have the Vans Cirro and they fit true to size so if you measure your feet and it says a size 9.. it's usually a size 9. Also the double boa system allows you to adjust the lower half and the upper half of the boot with 2 little knob that twist. The lower portion of the boot does create a little pressure (could be because I didn't break them in yet) if you just simply twist them in so you'll have to play with the setting a little and it'll be fine. I would only recommend this boot to someone with a narrow feet because the lining of the boot is pretty cushy so if you have a wide feet please avoid this boot. Other wise I would say the boot would pack out by half a size at most.
