Just checked out the primal 3. My husband hated how it felt in the 3. Primal 2 was a much more comfortable shoe for my husband. Any suggestions for a different brand that is as flexible as the 2 is with the heel.?
For Lems, the Primal models are the most minimalistic, so he might want to look into Xero Shoes. Maybe the HFS model, or Dillon if looking for something casual. Those shoes will have a lot more flexibility and ground feel.
I'm not 100% sure. It appears like they added half sizes and the overall toe box width is comparable. I find these to be wider feeling than some of the other Lems models.
