mine usually are, but im a bit ocd and have to have it even lol having it on different notches is fine, it could be a few things, no two snow flakes are exactly the same and neither are two boots. the way the padding broke in may be a bit different for each foot. and also, your feet are different sizes. everones are, but some more than others. not usually noticable, but in a boot it could pack the padding a bit differently. as long as they feel the same on each foot, which is should, it doesnt matter whos buckle is where.
