How to Read Offset Cracks (Palm Facing In or Out?)
An offset crack—where one wall sticks out further than the other—can either work massively in your favor or leave you slipping off completely. It all comes down to where your palm faces relative to the offset wall.
Here is how to read and handle offsets based on jam size:
1. Finger Cracks: Backs of fingers to the offset Keep the backs of your fingers against the offset wall so you can perform the correct palm wrap for your finger jams (something we teach in Global Crack School).
2. Thin Hands: Palm towards the offset Press the palm and thumb pulp directly against the offset wall. This gives you extra friction and keeps rigidity through the jam.
3. Hand Cracks: Since your hand fits fully inside, use the offset for body positioning. Either “jamback” with feet against the offset for speed, or shuffle with your shoulder against it (if it’s large enough) if you need to go slower and comfortably place gear.
