Being simple and short:
Very well designed and you can feel that the product is high quality. The size fits flawlessly and you can still have the barefoot feeling from your shoes.
I strongly recommend for those who walk a let during the day, or for people that are starting thei´re Barefoot walking journey.
painfull on my feet
I am a big fan of the shoes that vivobarefoot offers, but ithese insoles are really painful walking with them. It feels like the perforation in the insole is squeezing in the bottom of your foot. I've tried wearing them barefoot and also with socks.
I'm using this insole for the Gobi II. I have been comfortable wearing the show at 5°C. It does take a bit from the minimal feel that the shoe has without insole (as i normally wear them), but it is worth it to keep my feet comfortable.
