I tried them but didn’t get on with them 100%. I wasn’t a fan of the material in between my toes and also that my toes weren’t all the same length as the little pockets for them. Also they felt rounded at the bottom of my feet rather than trainers that project out slightly with an edge to them. This meant they didn’t feel stable to me.
I now have a pair of New Balance Minimus MT10 and they are brilliant. More secure on the foot. The sole is a Vibram one but it’s a bit thicker so you don’t feel every stone, but retains the barefoot feel. They also have a 4mm drop from heel to foot which feels more comfortable to me.
All in all they are a VERY minimal trainer rather than a total barefoot effort and felt far better for it. You still need to forefoot strike, etc, and they are brilliant for weight lifting on top of that. They also don’t look weird/try hard.
