Runspeed changes based on environment

[RazaelsTree]

Sometimes I'll be running(not encumbered) with Jboot effect or SoW and my runspeed will become slow almost as if im walking. People told me that it was just seeming slower but actually I should be running same speed. I tested this and found my character was actually slowing down.

This happens a lot near zone canyons and such and throughout most of Nek forest I found(was a good example at least), another notable place where I've seen it was the rathe mnts zoneline in feerott.

I tested this and found that I am actually running slower by having my summoned pet following me and he is able to catch up/keep up even with Jboots on(whenever im experiencing this phenomenon). Also mobs that normally cant catch me can sometimes catch up and hit me because of the slowdown.

Anyone else experience this and know what may be the cause and or solution?
