If they are both Enhancement Bonus, No. Just the greater will apply.
Are you beyond light carry capacity? Are you using Medium or Heavy Armor?
I wear heavy armor. I don't really carry very much in my bag. But I dunno what the light carry capacity is.
Run speed can be Reduced by
Not an AoE, but quite effective.
Well I have a good amount of STR and my character has the heavy armor training or whatever.
Heavy Armor weight can vary, some are listed as 35lbs (banded mails) and others can reach 50lbs (fullplates), so is a burden on your carry capacity .
Bonus type. bonus type. bonus type.
For movement speed when it comes to gear, nope; all the gear out there is movement enhancement bonus. There's is stuff like sprint action boost in heroic trees and other effects like barbarian speed, bard speed, etc. that gives more movement speed that stacks. (other type effects tends to have quite a few stacking options via gear, but movement speed is something the game heavily limits)
As a general rule, you can assume no. Most things will not stack. Equip the highest single bonus item for each stat and ability you can find. The exceptions to this are usually pretty obvious. +6 Strength +2 Exceptional Strength +1 Quality Strength Each of those has a different qualifier in the title and the description will have a different bonus type so they would all stack with each other.
Interesting. I mean, I'm not gonna sweat it now since I regularly cycle gear. But I imagine this will make late game gearing very tedious. It sounds like the game favors having gear pieces that do one thing very well as opposed to gear that has multiple bonuses.
Lots of stuff stacks. And there's even some gear where it's very much multiple things on a single item that stacks; like with these bracers with fort, insightful fort, and quality fort:
