I've got the 2021 on a couple of pairs of Baker's Oxfords and a Cougar boot. Bottom line, I find them softer than the 430, 700, 269, etc. and have no problem with them on wet surfaces. As you would expect, they wear a bit quicker than the other soles. I really like the sole a lot and find them comfy, though it seems getting the 2021 means giving up some of the arch-ease support.
