The “Foot Of The Mountain” boots have option that says-
-100% of Dodge Rating converted to Endurance Threshold while you have at least 1 stack of Mountain’s Endurance.
I tested the option by adding flat dodge and % dodge rating, as well as using skills, passives & items that increase my dodge, but nothing increases the Endurance Threshold other then the amount of HP my character has. No matter how much dodge i have or from what place i get it, the option of the boots doesn’t react with it.
