Here is my take, I am never barefoot and surely was never barefoot often as a child. I lived in the city, I wore shoes. I wore slippers around the house... even now I usually have something on (even just socks) unless I'm sleeping.
It's..weird.
You feel everything. Suddenly what your foot DOES when you walk is noticeable since there is no cushion to make it less so. I stand on my tippytoes and ball strike HARD and LOUD when running/walking, which in regular shoes has enough cushion to kind of pad my foot but in these.. I feel it. Especially my running form, it's like retraining how I run because I can FEEL my foot hitting pavement wrong.
and suddenly my pretty normal stance of standing on tippy toes when not moving feels like a workout. which is weird.
I am pretty sore (my achilles tendon especially) then again I was an idiot who went running in them before my feet were ready. So now I'm back to square one and just walking in them to walk Merlin or other dogs.
Overall, I like them. I think once I get more used to walking and get back to running in them slowly they will be great.
The only thing I do not really like is that it POINTS OUT OBVIOUSLY the ways I am running incorrectly. Things that were silly little mistakes or just technical stuff in my nike frees and BLARING mistakes in these because I can feel everything. Which I do like but I don't lol I don't because it's annoying but I know overall it's good for me to know these things I'm doing wrong
