Just recently bought the Connect 2 and since I already have the Connect it’s time for a little comparison (you can read my review for the Connect before this one if you want). Besides just one colour variant there is now welded overlays on the upper. This does give the shoe a tad bit of rigidity which I like. They also have the tieless shoelaces that come on by default with the optional rope laces as with the Connects. I haven’t decided yet it I will cut them off and go with the ropes or not.
OK so the most obvious change is with the insole. It’s now removable and made from Ortholite (you can look it up if you want) and it does have a pretty equivalent dampening vs Poron with the Connects. This also means you can use their new rock plate with it (I also did a review for that). I also believe if the Connects just fit you then go up a size with the 2nd gen as there seems to be a less volume.
With that said the ground connectivity is just a tad less vs the Connects but still very good. Also with the new insole your feet will slide some if you use socks. Since I won’t be using socks very often this is good. Even worse if you use their rock plate and socks then your feet are really going to slide around. In the end for me I give the Connect 2 just a .25 bump in rating over the Connect @4.25 out of 5. The difference was the added welded overlay.
