These boots are from the Shaman Thurgadin Armor Quest. I was told that your suppost to lose endurance/stamina whatever it's called when you swing your weapon depending on the weight and that is why these boots are useful. From what I've noticed since playing on here, you only lose said endurance/stamina when you jump, cause I have even lost any when activating disciplines on my monk or even running. If this mechanic isn't being used for whatever reason or what I was told may wrong that is fine, just wondering if there is planned changes for the boots, the wiki had them listed as what shown below, same as allakhazam, which I then changed the wiki to the above stats cause that is what you actually get.
