Sure-Footed is a Skill used by Modern Sonic and Classic Sonic in the console/PC version of Sonic Generations. When equipped, this Skill prevents the playable character from being stunned after taking damage.
When using Sure-Footed, Classic/Modern Sonic will instantly land on his feet after taking damage, effectively eliminating the mechanic that would otherwise stun Classic/Modern Sonic and knock him off his feet for a couple of seconds whenever he gets hurt.
To unlock Sure-Footed, the player can buy it at the Skill Shop from the beginning of the game for 500 Shop Points. It can be equipped to both Classic and Modern Sonic and costs 20 Skill Points to be equipped.
