Okay so far

Tighter than other vivos I've had,but they're loosening up after a bit of wear. Will be used for hiking etc eventually


So I've been having some knee pain after running, only doing 3x 10km a week.
I thought I would see if barefoot shoes actually where as good as everyone claims.... Much to my surprise I have done 10 runs in these since buying them and I love them! No knee pain. You definitely have to follow the advise, gradually increase your distance over time as your feet and calves will now know what real running feels like! Foot strength has increased and so has my stamina.
I ordered the next size up as I'm a half size and there is plenty of room for my toes to splay, but your foot will stay secure enough not to move around.
Would highly recommend these shoes.
Will be trying the casual ones out Rey soon.

Awesome shoes

Absolutely love my vivobarefoot trail fg! Such a great pair of barefoots. I haven’t really worn any other shoes besides my basketball boots. I’ve done a lot of walking, hiking and training in them and they are amazing. My feet already feel better and stronger. Slowly getting some more range of motion on my ankles too. Great product, can’t wait to get my next pair!
