These are my first Vivos, so not able to compare to other styles, but as compared to other shoes in general, the Rif Eco cannot be beat. Incredible comfort right out of the box. Going "barefoot" has felt great on my feet, knees, and back. As a yoga instructor I love to move my body, and moving through the world with these shoes on leaves me feeling grounded, stable, and solid in movement. And apparently they're super stylish, as compliments continue to roll in. Can't recommend them enough.
I have had a couple of pairs of ra's over the years and this is a great replacement, very comfortable!
Really nice smart shoe
This shoe is actually quite a bit smarter than it looked in the pictures on line. I was going to use them to knock about with but they need to be elevated to a smarter category.
