If you’re a fan of Lems signature barefoot shoe the Primal 2, it just got a big update, so lets go through the changes.
The main change I see is in the stiffness of the sole. The outsole is stiffer, and the insole is slightly stiffer and thicker. You can see that in this video, where the Primal 2s are easy to fold up both length and width-wise. I can still fold the Primal 3s both ways, but there’s more resistance.
