Bro every 29.5 fits completely different. I highly recommend you go to a bootfitter and then search for a used pair of the boots that fit you. Buy them some beer or buy something else from shop since you are using them essentially.
You're reaaaallly going to regret this otherwise. For example: My 29.5 FT Classics fit like some 27.5 Sals I've owned as well as some 28.5 Atomic Hawx I almost purchased...
