Sure Feet Feat 1
Source Pathfinder Core Rulebook
Whether keeping your balance or scrambling up a tricky climb, your hairy, calloused feet easily find purchase. If you roll a success on an Acrobatics check to Balance or an Athletics check to Climb, you get a critical success instead. You're not flat-footed when you attempt to Balance or Climb.
