The feet have changed.
RLD's on the left, Adrenaline on the right.
The Adrenaline feet can be screwed in to reveal the spike.
The RLD-3 need the booties removed to reveal the spike.
IMO, advantage Adrenaline.
They are easier to use and you can’t lose the covers.
Also the rubber on the RLD’s is much harder.
Not sure how this will play out for longevity.
The RLD’s slip easily on a smooth floor, the Adrenaline doesn’t.
