Not everyone is perfectly symmetrical, for example my left leg is longer than my right. Actually the hip is lower, etc. To compensate for this i point my left foot down and make my right foot level. To find out if u r all even, sit down with ur feet in front of u and have someone draw a line or mark where each foot is. Not saying this is ur problem just saying it could be something odd like this.
Then adjust ur fit, people do it all the time, a little up, a little down, foreward, back. Dial it in until ur happy.
