Protect hardwood floors from gouging, add grip on asphalt, and support better than a bare kickstand on soft dirt. Not necessary, but why not? Fits Pletscher and Greenfield kickstands.
Three kinds: For single-leg kickstand; and for double-leggers, which we no longer sell, but we have a few feet for them; and for touring kickstands (the touring kickstands come with this "foot" so only buy a touring foot if your touring foot fell off on a ride or something). The feet aren't interchangeable. They're both a bit of a grunt to push on, but they'll go, and they don't fall off.
Note: sometimes Pletscher is out of the single feet, so we substitute Greenfield branded single feet. The Greefield single feet fit just as perfect as the Pletscher single feet but look a little different.
