The 580 boot is ideal for all experienced skiers. Thanks to the Flex adjustment, the boot can be made more tolerant (getting back into skiing, skiing with children, etc.) or more sporty (more responsive, more precise, etc.) The medium volume is suitable for most foot shapes while providing a very good compromise between comfort/support. The shell (much higher than on a standard boot) provides excellent coverage of the shins and spreads the weight very well. You choose!
