While snowboard boots should be a snug fit and may, at first, feel tight; they shouldn't hurt your feet. If you're experiencing pain, this could be because of excessive flattening of the arch that occurs during inward turns. When your foot flattens the ligament and your muscles at the base of your foot are stretched beyond the norm, which causes arch pain. To avoid heel and arch pain while snowboarding, tighten your boots and ensure you have the proper interior padding.
