Hi Frosty,I'm 5' 6″, 140 pounds, and a size 8 in women's boots. I just got a board with a width of 24.1. Your calculator suggest a 235 mm board. I stepped on top of my board with my boots (without bindings) and noticed that my boots are hanging out pretty far, esp the back foot on 0 degrees. The boot appears to be approx 1 inch over on the toe and heel side. Is my board not wide enough or am I doing something wrong, should I be at a greater angle? Many Thanks,Nancy
