Meh, sizing is all messed up nowadays. Street shoes I wear anything between a 9.5-10.5. Shirts seems to fit me pretty universally, pants however can vary greatly, some 32's are loose as hell, some are snug.
Ride boots are super small. I ride a 7.5 Burton a 7 in Thirtytwo and an 8-8.5 Ride. I sell Ride boots too and they are really short, but the toe box really molds and packs nicely. Buying them really snug is a good idea with the Intuition liner. But that's my preference. I love Ride boots, but they definitely run smaller than most brands.
So, you're probably a 10.5 or 11 in a Ride boot even if you ride a size smaller in other brands.
Just about everyone is gonna tell you that buying boots online is a huge gamble... you really never know what a companies sizing is. However, if you're planning on buying another pair of Ride boots then the sizing should be the same and you shouldn't have a problem... but in some cases the companies actually don't have consistent sizing so even then you can't he sure.
Bottom line, buying boots online is a big risk and It's so much better to just take the extra time and go try them on. It's better to do that than end up ordering boots that are too small or too big and it would definitely be bad to just use them anyways because you don't want to take the time to exchange them, its really important for boots to fit right, it could lead to some pretty serious injuries with your ankles.
