I’m sad to say that unfortunately I can’t do a full review, as I don’t walk when I play. which I don’t get to play as much anyway for a lack of time. so yes, as far as I can tell, they’re very comfortable and super stable. My SS is above 110 mph and my feet just stay anchored to the ground with no issues whatsoever. the reaction system does t leave any marks on the green from what I’ve noticed. Had the vapors, and yes, those were horrible for greens. As how they compare to the modes you mentioned, I can’t tell since I’ve never tried these on... Regrdinf your 3,4 &5 questions, I’ll have to get back to you at a later time or if someone else can chime in. like I said, I don’t get to play much, and I certainly won’t play when it rains. LOL Plus, our golf course Just shutdown for 2-3 weeks from city order... I hope I was still able to shred some lights on your inquiries... On a side note, somebody mentioned something about heel. I can say there is like a memory foam type on the inside and looks pretty snug. So I’d bet the heel would not come off that easily. I’ll take a picture of it tomorrow so you guys can see what I’m talking about.
