Hierarchically structured, superoleophobic surfaces are demonstrated that display one of the lowest contact angle hysteresis values ever reported – even with extremely low‐surface‐tension liquids such as n ‐heptane. Consequently, these surfaces allow, for the first time, even ≈2 μL n ‐heptane droplets to bounce and roll‐off at tilt angles. ≤ 2°.
