Based on the total weight of your gear, there should be a small chance that you stumble and fall down if you backpedal.
More weight = Bigger chance of falling down
also we could use thiS feature to buff Strength a bit.
For example : 100kg of total gear weight = 10% Chance of stumbling and falling BUT, for 15 STR and above, you get -1% chance of falling down, because your character is "stronger"
What do you guys think?
