I just ordered the mukluk advent x microshift in a L (im 6’3) for fall and winter trail riding. Did i do ok? First Fatbike

At 6’3″ I would think you need an XL?

I’m the same height and also bought an L. It fits fine. My only complaint sizing wise is it’s relatively easy to hit the chainstays with bulky footware but it’s a fatbike so not surprising.
